Browser hangs after clicking left mouse button on Industry News applet

Comment 1

[shrirang khanzode]

yuck...this is bad...used to work before.. nominating for nsbeta2. This is the 
first applet on the java website and it hangs the browser.

Comment 2

[shrirang khanzode]

Also, pressing the BACK/RELOAD button seems to freeze the browser(when hte 
applet is running). Most of the applets on sun site 
http://java.sun.com/applets/index.html show this problem.

Comment 3

shrir: do you happen to know the last time you tested this one?  I.e., when
might it have started to break?  That could help us narrow down to which daily
to look at, or if it's a difference in the latest build of Java Plug-In vs.
older build of JPI.

Comment 4

[Ron Gavlin]

FYI, browser hangs using IBM's 1.3 plug-in as well. It's been broken for at 
least a few weeks if my memory is correct.

Comment 5

[shrirang khanzode]

Let me backtrack this problem and get back to you. Thnx.

Comment 6

[rpallath]

Tried this with Branch M16-OJI-07102000 with Java Plugin version
1.3.0-netscape6-pr2

Does not hang.


Tried with mozilla  build dated 07/14/2000 (built from sources)
with above Java Plugin

Does not hang.


shirir: Can u specify the Java Plugin version that u are using.

Comment 7

[rpallath]

oops..
I think the bug is against Win2000.
I had checked it against WinNT.

Disregard my previous comments.

Sorry about that

Comment 8

[shrirang khanzode]

Hi, this happens for me on all flavours of windows. Even today's build 
(2000071408) shows the same problem .As soon as I click on the industry applet, 
instead of loading the news page, the browser locks up. 

Comment 9

[shrirang khanzode]

forgot to mention...java plugin packaged in daily builds on windows is 1.3.0

Comment 10

[Ron Gavlin]

I suspect the newer plug-in [e-mail] is testing against is not 
1.3.0. This brings up an interesting point. Who is responsible for 
maintaining/distributing the plug-in code, Netscape or the JVM vendor? If 
Netscape, how will you handle non-Sun JVMs like IBM's new 1.3 JVM which 
includes its own plug-in? Does Netscape or Sun forward plug-in changes to other 
vendors like IBM, etc?

Comment 11

[rpallath]

Tried this on Win2000 with Java Plugin version 1.3.0-netscape6-pr2.
on M16. and latest nightly build (07/14/2000).

It works  perfectly when  clicking on  'Industry news'
No hangs or crashes.

Ron: I'm testing this against 1.3.0 (the Plugin version does indicate that).

shrir: Could u specify the version of Plugin that u see on the Java Console.

Comment 12

Added myself to CC list

Comment 13

[Jay Patel [:jay]]

Putting on [nsbeta2-] radar. Not critical to beta2. 

Comment 14

[edburns]

I got a hang with the 2 June Java Plugin with JDK1.3.  With an 11 July mozilla 
build.  It appears to be hung in 

NTDLL! 77f677ef()
KERNEL32! 77f1c7d6()
JVM! 50447890()
MSVCRT! 7800248d()
KERNEL32! 77f04f2c()

Comment 15

[edburns]

Here's the infinite loop:

50447879   cmp         dword ptr ds:[504EE1A0h],edi
5044787F   jne         5044789C
50447881   push        edi
50447882   push        edi
50447883   push        0Ah
50447885   push        dword ptr ds:[504EE19Ch]
5044788B   call        50430AD0
50447890   push        0Ah
50447892   call        5043F145
50447897   add         esp,14h
5044789A   jmp         50447879

At this point, the stack trace is:

JVM! 5044789a()
MSVCRT! 7800248d()
KERNEL32! 77f04f2c()

Reassigning to Stanley.

Comment 16

[edburns]

Really re-assigning to Stanley.

Comment 17

[shrirang khanzode]

This is a bad bug and needs to be fixed for beta2.

Comment 18

[rpallath]

Ed, 

this is what I tried to simulate the same.

Installed JRE1.3 from (java.sun.com site).
Installed Mozilla

Now at this point I would assume that the  plugins (np*.dll) would be different.
Next,  I get the Patched Plugin (2nd June from Stanley) and unzipped it and just
copied the 3 np*.dll files to SeaMonkey/.../bin/Plugins dir.

Now I invoke mozilla, and try to load java.sun.com and click on industry applet.
This time it hangs as indicated in the bug.

But clearly I did something wrong here. I had just copied only the 3 np*.dll 
patched files. Not the rest of the files.
Clearly there would be a difference in the JRE1.3 from java.sun.com website and
that I got with this patched version ( 2nd june).


Now I unzipped all of the files from the patched version and copied all files
into the Progra~1/JavaSoft/Jre/1.3/bin and lib dir.

Listed below is all the files the patched Java Plugin contains
bin/
ActPanel.dll
beans.ocx
jpins32.dll
jpishare.dll
NPJava11.dll
NPJava12.dll
NPJava32.dll
packager.dll
plugincpl.cpl

lib/jaws.jar

So this time the npjava*.dll files in Mozilla Plugins dir. and in Jre/1.3/bin
dir. are the same.

This time when I try out loading java.sun.com and clicking on idustry applet, It
works perfectly. NO  HANGS.


Looks like,  this is  bug is against  wrong plugin version.

A simple check would be to, go to click Start-Setting->ControlPanel
U should see a java Plugin icon there.
Click on that. 
It brings upa Plugin Console window.
Check the 'show Console' option
Clikc Apply.
Close it.

Invoke Mozilla.
this time the Console would show up and the version of the Plugin  will show up.

It should read 
Java (TM) Plug-in Version 1.3.0-netscape6-pr2
Using Jre Version 1.3.0 Java HotSpot(TM) Client VM.


This is the latest Patched Plugin available and  I presume this is the one u are
checking the bugs against.

Shrir /Ron Could somebody  list out the Plugin version u see on the Java Plugin.
Console.

Comment 19

[Ron Gavlin]

When using IBM's 1.3 JRE, the console displays:
"Java(TM) Plug-in: Version 1.3.pj"

When using Sun's 1.3 JRE, the console displays:
"Java(TM) Plug-in: Version 1.3.0-C"

Both of these hang Mozilla when clicking the Industry News applet. How is the 
newer Java Plugin version 1.3.0-netscape6-pr2 distributed? Do I have access to 
it?

Comment 20

[shrirang khanzode]

The java console says this... " Java (TM) Plug-in Version 1.3.0-netscape6-pr2
Using Jre Version 1.3.0 Java HotSpot(TM) Client VM."

Comment 21

[rpallath]

I think  George  Drapeau would be the person to address this issue.

Ron, Looks like Shrir has the correct version of the Plugin.
I'm outside Netscape and do not have access to installer/commercial builds of
Netscape (which bundles Sun Java).

But I do think the netscape6-pr2 version should have made it into  Netscape.
George, Am I correct?

Comment 22

[drapeau]

Raju: yes, you are correct, although I expect there to be one more drop from
Sun.  Right now, the current drop of Java Plug-In for Windows should say what
Shrirang says (see previous bug comments).  It is a build from June 2, 2000, I
believe.

Comment 23

[rpallath]

Shirang, did u install the Sun Java using the commercial build or did u download
it off the java.sun.com website and then apply the patch.

Comment 24

[shrirang khanzode]

I installed the daily commercial build which packages the jre and the patch.Did 
not go to java.sun.com.

Comment 25

[stanley.ho]

I tried out the test case, but I didn't get the browser to hang. Shrirang, can 
you try to install the JRE 1.3, and apply the patch manually as Raji pointed 
out to see whether it works for you?

Comment 26

[shrirang khanzode]

build:2000072008
Strangely, after I manually installed the jre and added the patch (and replaced 
the dll files in mozilla|plugins folder with the new ones timestamped 05/22 from 
the jre/bin/ folder) I cannot even launch the browser. I can see an error 
message in the console saying " Java HotSpot Client VM warning: setting of 
property "java.compiler" is ignored.
Error occured during initialization in VM 
java/lang.NoClassDefFoundError : java/lang/object "

and the console quits.

I will retry with today's latest build and comment.

Comment 27

[rpallath]

Shrir
The plugins cannot be dated 05/22. SOmething is wrong.

Try this (this is what I did).

1) Install Java 2 SDK.
 this will create c:\jdk1.3 and 
 c:\programFile\javasoft\jre\1.3

This is the FCS version available from java.sun.com
(It should be the same bundled thru' Netscape installer).

2) then, Get the patch. (I have it as a ZIP file)
   Thru' Winzip extract it.
   This will create a bin and a lib dir.

3) Copy all contents of this bin dir. to c:\programFiles\javasoft\jre\1.3\bin
4) copy all contents of lib dir to c:\programFiles\javasoft\jre\1.3\lib  
(jaws.jar is the only file that will be found in this lib dir.).

5) remove npjava*.dll files from Mozilla Plugins dir.
6) copy c:\programFiles\javasoft\jre\1.3\bin\np*.dll to mozilla\Plugins dir.

Now we are all set. Try this out

Comment 28

[shrirang khanzode]

Attachment: jre patch zip file.

Comment 29

[shrirang khanzode]

Raju, I did exactly what you have mentioned. The patch file in the packaged 
builds is attached. It says 05/22/2000 5:54 pm for the dll. files at least 
for sure. I dunno what I am dong wrong here..but will try the automated build 
today and try to figure out what's missing from my side.Thnx.

Comment 30

[rpallath]

I just tried it out.

I just unzipped you attchmt.

Copied the bin and lib directory files to c:\programfiles\javasoft\jre\1.3 bin
and lib dir. respectively.

Copied the np*.dll files to mozilla plugins dir.
dated 05/22.

It did bring up the browser and the Console window.
The JRE version reads 'stanleyh'

U are using an old verion of the patch.

Comment 31

[shrirang khanzode]

Just got an email from George that he sent the latest jre bits to put in the 
daily packager here. This should guarantee that we are using the same bits. I 
will recheck this bug after the new jre bits are in the builds. Thanks!

Comment 32

[shrirang khanzode]

I do not see the 'Industry News' applet on the java.sun.com page at all now. 
Seems like the webpage changed...hmm?

Comment 33

[drapeau]

shrir: I just went to java.sun.com and looked at the page source.  Mid way 
through the page is the following comment:
!-- --------------------Removing for maintenance of industry.java.sun.com

I don't know why this is, or exactly what this means, but it's pretty clear that 
the Industry News applet is disabled for now.

Meanwhile, after looking at this bug some more, I'm starting to think that it's 
another symptom of a meta-bug.  I believe bug 8290 is also a symptom of the same 
meta-bug.  The OJI group talked about these similar-looking problems last week, 
and we are starting to think that it's race conditions, or an imprecise 
definition of applet lifecycle that's the problem.  We're working on it now; as 
a matter of fact, Stanley Ho is about to check in a possible fix for 8290 in the 
next 24 hours (it was due tonight, Stanley's time permitting) on the trunk.
For PR 3, one of our major tasks is to get the lifecycle problem better defined 
and fixed.  When we do that, I believe a few of these bugs will go away.

Comment 34

[shrirang khanzode]

Thanks for the update, George. I will be on top of these bugs to verify.thnx!

Comment 35

[shrirang khanzode]

woohoo...this is working on the m17 branch build on windows NT (2000080404m17). 
Will verify once I check this on the trunk build as well.

Comment 36

[shrirang khanzode]

This is not happening anymore. With the new jre patch being applied in today's 
build, the browser does not freeze/hang. Verified on win2k/NT with build 
2000081508M18.Marking FIXED.

Comment 37

[shrirang khanzode]

verified.
