JreMemoryLeakPreventionListener for JBoss 5.1

[xmedeko]

Hello,

we use JBoss 5.1.0GA and have a memory leak, highly probably caused by JasperReports and sun.awt.AppContext JRE memory leak. The new Tomcat 6 has a class JreMemoryLeakPreventionListener to prevent this kind of leak. Is there any way how to port this class into JBoss 5.5.

Or, I think I just neet to run the code

javax.imageio.ImageIO.getCacheDirectory();

by the system (common) class loader. So the question is, how to execute some code by the system class loader in JBoss - either when the JBoss starts or then the Tomcat 5.5 starts up.

Thanks

Andt

We don't plan to add the memory leak preventer of Tomcat6 in Jbossweb for the moment.

Thanks Jean-Frederic for your reply. Do you know how can I perform this opperation before Tomcat starts in JBoss 5.1.0?

JBoss 5.1.0 doesn't use Tomcat but JBossWeb. I don't think that this Tomcat listener will work in JBoss.

I hope I just need to run the code

javax.imageio.ImageIO.getCacheDirectory();

before the JbossWeb starts. I think I do not need Tomcal Listener, maybe some kind hack or start hook could do the job.

Hello,

Are there any plan to enable the memory leak preventer on JBoss Web 7 ? I've found several ClassLoader memory leak issues on AS 7 and such a component would help a lot to resolve them..

I'll post more details about the different leaks I've found soon.

It is not planed for the moment.
