[jboss-jira] [JBoss JIRA] (AS7-6776) Memory leak with ServletContainerInitializer

[Stan Silvert (JIRA)]

    [ https://issues.jboss.org/browse/AS7-6776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762656#comment-12762656 ] 

Stan Silvert commented on AS7-6776:
-----------------------------------

Looks like I have a fix.  I just remove the attachment in ServletContainerInitializerDeploymentProcessor and the problem goes away.

public void undeploy(final DeploymentUnit context) {
   context.removeAttachment(ScisMetaData.ATTACHMENT_KEY);
}

I don't know if this is really fixing the root problem though.  What do you think?

> ServletContainerInitializers are not cleaned up on undeploy.  This causes a memory leak.
> I'm attaching a couple of maven projects to reproduce the problem.  The first project creates a jar with an SCI that allocates 50MB.  The second project is a plain war that packages the SCI's jar.
> Redeploy the WAR several times and you will get an OOME.
