When I run java, i see that an extra reference count is added to the component manager an is never released. This causes a warning assertion to be fired at xpcom shutdown.

Need traction on this bug
Reporter, Can you try out JRE 1.4.2 beta (download from http://java.sun.com/j2se/) and see if there is still a leak there?

Doug, Could you please verify this bug, or tell me steps of how to test this by providing the test case or something. I think we need debuggable to test this, right.

Steps to verify: + install the JRE as suggested. + build mozilla. + set XPCOM_MEM_LEAK_LOG=leaks.log + run mozilla. + load a page with a java applet tag. + exit mozilla + paste the leaks.log file to this bug.

sorry for the format, contrast to the situation that have not used java, I only found nsHashKey/nsHashtable 's leak is relate to Java

Try uninstalling java. From what I remember, most of those leaks are related to the JRE plugin holding onto references when loaded.

Joshua, you may need to file a bugtraq bug for this. Thanks!

OK, I also check OJI. I think nsHashKey/nsHashtable 's leak is from OJI/ProxyJNI.cpp
|
||
Comment 15•17 years ago
|
||
I tested with JRE 1.5 which hasn't shipped yet. The problem seems gone.

compare the leak.log (with and without java plugin installed), the following object leaked when java plugin (1.4.2) installed: nsComponentManagerImpl, nsJVMManager, nsHashtable, nsLocalFile, nsPluginHostImpl, nsVoidArray when switched to jre1.5.0, leaking of nsJVMManager is gone, but same results for other objects. attached balance tree shows the nsPluginHostImpl was Addref 3 times when call JavaPluginFactory5::Initialize which is inside JPI code.

Kyle in comment #17 > bug 88311 is for the same thing. Kyle, are you saying 88311 is a dupe? or do you mean it is the same _type_ of thing?
