108242 - Java applet fails to make HTTP connection, throwing access denied exception or even locking up, when called from Javascript

Status: VERIFIED WORKSFORME

(Core Graveyard :: Java: OJI, defect)

Description

[Piotr Pawlow]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
BuildID:    2001101117

Clicking on any of the links at http://pp.siedziba.pl/mozilla should open a pop-
up window with "Test passed!" message in it. In Mozilla the first link causes a 
deadlock, the second displays a window with "null" text and "access denied" 
message on status bar, only the last one work as expected.

Reproducible: Always
Steps to Reproduce:
1.Load the page at http://pp.siedziba.pl/mozilla
2.Wait for the applet to finish loading
3.Click on the links

Actual Results:  Link 1 - deadlock, browser doesn't respond
Link 2 - messagebox appears with "null" message in it
Link 3 - messagebox appears with "Test passed!" message

Expected Results:  "Test passed!" message should appear in all cases.

Looks like test #2 fails due to Java Plugin bug #4473593, and it is duplicate 
of Mozilla bug #86437. It works fine after installing JRE 1.4.0 beta 3.

Test #1 seems to be a different problem, though. At the first glance it doesn't 
seem to be a Java bug since it works on Internet Explorer with Java Plugin 
installed as default Java Runtime. I will try to investigate more on this 
problem.

Both of the remaining tests run just fine with the MRJ plugin for Mac OS X (as
of v1.0d5).

I have modified com_thread.java file a bit so I could see on Java Console how 
far it goes. In my case it freezes at line:

OutputStream os=c.getOutputStream();

It won't go any further until Javascript call to document.comapplet.post() 
returns. Then it continues execution. See test #4 at 
http://pp.siedziba.pl/mozilla. This test freezes the browser for 10 seconds, 
then displays "null" (should display "Test passed!")

Confirm bug on windows2000 bug works for me on Linux

Comment 9

Yes, this bug is Windows specific. I have retested it on Windows XP using Mozilla 1.2, Phoenix 0.5, with Sun's JRE 1.4.1 - result is the same. However, it works fine on my Linux box.
