Ales Nosek updated IVY-1332:
----------------------------
Attachment: ivy_eclipse_memory_analyzer.png
build-caller.xml
build.xml
Start this test case with:
ANT_OPTS="-XX:MaxPermSize=20m -XX:+PrintGCDetails
-XX:+HeapDumpOnOutOfMemoryError" ant -f build-caller.xml
> OutOfMemoryError: PermGen caused by IvyContext leaked when building
> subprojects
> -------------------------------------------------------------------------------
>
> Key: IVY-1332
> URL: https://issues.apache.org/jira/browse/IVY-1332
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Reporter: Ales Nosek
> Attachments: build-caller.xml, build.xml,
> ivy_eclipse_memory_analyzer.png
>
>
> The build.xml files of my subprojects include Ant's <taskdef/> element to
> define Ivy tasks. This element causes creation of a new classloader to load
> the Ivy jars.
> The code from IvyContext.java:
> public class IvyContext {
> private static ThreadLocal/*<Stack<IvyContext>>*/ current = new
> ThreadLocal();
> ...
> }
> This static initialization runs once with every classloader and creates a new
> ThreadLocal object every time. All those ThreadLocal objects are visible
> (referenced) from the main Thread. For 12 subprojects I end up with 12
> ThreadLocal objects each containing one Stack holding IvyContext objects. The
> IvyContext objects point to its class which points to its ClassLoader. The 12
> ClassLoaders stay retained.
