Adrian Brock commented on JBWS-2615:
------------------------------------
The information on this "bug report" is not enough for me to
reproduce/understand what is happening,
but it certainly doesn't look like a classloader issue, instead it how the classloader
is being used.
The only things of interest shown in the screenshots are:
1) repeated loading from the same class (which is impossible if it is the same
classloader - defineClass would throw an error)
2) loaded classes not getting unloaded, i.e. garbage collected
(1) could only happen if there are multiple classloaders being used,
this could be further investigated by attaching trace logging for org.jboss.classloader
showing
which classloaders are loading the classes (and how those are constructed)
(2) is an issue for whoever holds the hard reference(s) on the class(es)/classloader(s)
this could be investigated with a heap dump and the java6 tool jhat

Key: JBWS-2615
URL: https://jira.jboss.org/jira/browse/JBWS-2615
Project: JBoss Web Services
Issue Type: Bug
Security Level: Public(Everyone can see)
Environment: Windows 2003 Server, JBoss 5.0.0.GA, Java 1.6.0_12.
Reporter: Edson Goncalez
Priority: Critical
Attachments: generated_source_classes.zip, screenshot-1.jpg, screenshot-2.jpg,

We have an application that comunicate with a webservice (Federal Government of Brazil)
constantly, step by 5 or 10 seconds.
We have created web service consumer classes by using the following command point to the
WSDL file:
wsconsume -k -p br.com.compliancefiscal.nfe.ejb.sefaz.ws.nfestatusservico -v
NfeStatusServico.wsdl
This tool, was generated this classes:
NfeStatusServico.java
NfeStatusServico_Service.java
NfeStatusServicoNF.java
NfeStatusServicoNFResponse.java
NfeStatusServicoSoap.java
ObjectFactory.java
package-info.java
The problem is. When running... every call this webservice generate a new loadclass.
Viewing in the JConsole tool, we can note that whe app starts it have aproximatelly 15000
classes loaded, and afeter 10 hours running we can se that the jvm has increased up to
70000 classes loaded, and only 252 classes unloaded.
I have the screenshot that show this.
What can occours to causing this BIG load classes for same class ?
PS: The app does not run any other service. It just start a method that connect to the
specified webservice and return a String info. A TimerService trigger start the process
steb by 5 seconds.
Thanks.
Edson Gonçalez.
