Comment 2 Petr Pisl 2005-03-07 15:02:40 UTC 
The problem is described
http://issues.apache.org/bugzilla/show_bug.cgi?id=26135 . 

So we will have to wait for a new version of Tomcat or downgrade the
bundled tomcat to 5.5.4 version.
Comment 3 Sherold Dev 2005-03-07 16:02:20 UTC 
Please note that this issue was reported on Tomcat 5.5.4 as well.
Comment 4 Petr Jiricka 2005-03-10 17:30:21 UTC 
Radim offered to look at this - thanks Radim.
Comment 5 _ rkubacki 2005-03-15 13:50:08 UTC 
I am testing Tomcat 5.5.8 now with some app from Petr Pisl that employs various
technologies - JSF, Hibernate + some other libs. Although it cannot connect to
DB in my env it leaks if I deploy it, show the welcome page, undeploy.

My current suspicion is that it can leak through naming context -
org.apache.catalina.loader.WebappClassLoader@31b5
instance org.apache.catalina.loader.WebappClassLoader@31b6
    held by org.apache.jasper.compiler.JspRuntimeContext@1212b
    held by org.apache.commons.modeler.BaseModelMBean@19499
    held by org.apache.naming.ContextBindings.clNameBindings
    held by org.apache.commons.logging.LogFactory.factories
    held by org.apache.naming.resources.DirContextURLStreamHandler.clBindings
    held by org.apache.catalina.loader.WebappLoader@46fc
    held by org.apache.naming.ContextBindings.clBindings

I am not sure who is responsible for bind/unbind here. Maybe it is problem of
Hibernate.
Comment 6 _ rkubacki 2005-03-15 17:10:24 UTC 
I cannot reproduce this with simple web app that loads several classes and runs
System.gc() during page execution. Redeployed >25 times and it seems that
classes are unloaded correctly
Comment 7 _ rkubacki 2005-03-15 17:42:17 UTC 
I enhanced the example with (failing) lookup for JNDI context and still it is
OK. Sounds to me like a problem with components in Petr's application. I would
like to close this as WONTFIX - we surely know that it is not NetBeans problem.
We cannot tell for sure if it is problem in Tomcat.
Comment 8 Petr Pisl 2005-03-16 09:38:54 UTC 
I agree.
Comment 9 Jaroslav Pospisil 2005-03-16 09:54:31 UTC 
I agree too.
Comment 10 Petr Jiricka 2005-03-16 09:56:27 UTC 
Marking as WONTFIX.
