I have an applet that tries to read a no of JSObjects (approximately 1000 to 
1100) in its init method. I need to initialize the applet based on a request 
Parameter whose value is coming from a select box. When I initialize the applet 
one after the other (I have to do this and this is not done for fanciful 
testing), after 4-5 iterations the mozilla browser crashes. The 1st 3-4 
iterations will initialize the applet well. But from the 4rth of 5th iteration, 
mozilla crashes. This is happening in both mozilla 1.5 and mozilla 1.7 and for 
both the jre versions 1.4.2_05 and 1.4.2_02 (Sun jres). I am using Red hat 
linux 9.0. 

Mozilla crash was occurring at the native code of the getValue method of the 
JSObject. That is, crashing was occurring at the native code outside JVM. It 
was seen that this problem was occurring at the various points in the code 
where the JSObject were being read.

In the directory  /usr/local/mozilla/plugins I have a link named -> /usr/java/j2re1.4.2_05/plugin/i386/ns610-
gcc32/ I guess this is what was needed instead of copying 
the whole of
Also, I have done the maximum performance enhancement to avoid reading the 
JSObjects as much as possible.

But at the same time the crash not is occurring in IE. (I am using IE version

INTERNAL ERROR on Browser End: Pipe closed during read? State may be corrupt
System error?:: Connection reset by peer

Reproducible: Always
Steps to Reproduce:
1. Write an applet that calls close to a thousand JSObjects getValue method.
2. Call that repeateddly

Actual Results:  
Then the browser crashes after some iterations (4to5)

Expected Results:  
The applet should be initialised properly.

This is happening in both mozilla 1.5 and mozilla 1.7 and for both the jre 
versions 1.4.2_05 and 1.4.2_02 (Sun jres).

brendan: is it likely/possible that liveconnect isn't rooting an object it's
exposing to java and the object got gc'd?

reporter: please install a talkback enabled build and crash again,
the run components/talkback and copy the incident id to this bug. thanks.

you could also build your own mozilla (make sure you don't --enable-strip.
personally i'd go for --disable-debug --disable-optimize, but you could pick
enables if you wanted to) of mozilla and use valgrind. this next bit is rebuilt
from memory...
export VALGRIND_OPTS=--num-callers=10 --error-limit=no --logfile-fd=3
./ `which valgrind` ./mozilla-bin
you'll eventually want to add something like:
 3> mozilla.valgrind 2> mozilla.stderr 1> mozilla.stdout

The bug 285451 that has been marked as a dupe of this bug was already confirmed
and its status was changed to new. The Talkback crash ID of that bug was:
4221939 and the page to reproduce it is: So I
believe you do have a reason to set this bug to new.

Sorry for this, but I'd like to ask you to try to give some attention to the bug
because the application we develop depends upon this and we're obligated to use
IE, unfortunally. Besides that, this kind of situation is very common. So if you
can give us some idea on when this is going to be fixed I'd be grateful.
Kyle, could you look into this for 1.8b2?  I'll help get drivers approval if you
get a patch that fixes this bug attached.

Reporter, jre 1.4.2 is buggy when doing liveconnect calls in applet's init
method. We fixed a bunch of bugs for this in jre 1.5. Could you upgrade to jre
1.5 and try again?

Giovani and Bob, I can not get mozilla crash using the testcase you provided,
neither on WinXP nor on Linux, with jre 1.5.0_01. The value in textbox can be
successfully increased to 999. Is there any special operation needed to make the
crash happen?

Comment 8

There is no additional operation to reproduce the crash. I'm using jre 1.5.0_2
under windows XP SP2 and it crashed when I opened it, it has counted until 39
then it has broken. 

I've downloaded the latest nightly build available on the Firefox's main
developer's page and it has crashed as well.

So, I've generated a new talkback on the latest nightly build. It's id is 4950682.
So this affects the 1.5 release of the Java plugin, and the crash is in caps
code.  Talkback link:

This is a bug in java plugin and affect all version of jre1.5. I talked with the
java plugin developer and filed sun bug 6254466 for tracking this issue. The
root cause for bug 264062 is the same.

Awesome! But isn't there something that has to be done on Firefox side as well?
To my understanding it shouldn't be crashing if some plug-in misbehaves.

Tested with intel Mac running Mac OS X 10.4.11 with all current updates, and Camino nightly version 2.0b2pre ( 2009020512).

No crash; but the applet had problems working properly.  Attaching Activity Monitor sample from Camino while the applet was running

Activity Monitor sample from Camino

Sample taken while applet on Caltrans URL was running.  Should have made that clear in the previous comment.

File a new bug and attach the activity monitor there. Don't hijack old bugs.

I'll let Alfred deal with this bug's status.

Testcases in comment 5 and comment 20 are no more available.
Is there any way to reproduce this bug?

Re comment #26:  

That is what happens when an actual error is reported and no attempt is made to correct it for more than six years after good test cases are presented.

Firefox code moved from custom Liveconnect code to the NPAPI/NPRuntime bridge a while back. Mass-closing the bugs in the liveconnect component which are likely invalid. If you believe that this bug is still relevant to modern versions of Firefox, please reopen it and move it the "Core" product, component "Plug-Ins".
