[Ales Justin (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12725282#comment-12725282 ] 

Ales Justin commented on ISPN-2372:
-----------------------------------

>> I believe we start new caches for each app - Aleš knows the details regarding this.

We actually start 8 caches for each app.
They need to be eager started, so any M/R tasks, jobs work as expected; see ISPN-2353.

> {{AbstractJBossMarshaller.marshallerTL}} is leaking {{PerThreadInstanceHolder}} instances. These hold a reference to {{MarshallingConfiguration}}, which indirectly holds a reference to the classloader, which of course holds a truckload of stuff.
> The cause of the leak is the fact that noone ever calls {{remove()}} on {{marshallerTL}}. 
> I've tried adding {{marshallerTL.remove()}} to {{AbstractJBossMarshaller.stop()}}, but this only removed references from JBossAS' MSC Service threads. Other threads (in my case only one thread - "http-/127.0.0.1:8080-2") are still causing the leak.
