[jira] [Commented] (FELIX-3553) Use of parallel class loading capability of JDK7

["Ulf Lilleengen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-3553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13504687#comment-13504687 ] 

Ulf Lilleengen commented on FELIX-3553:
---------------------------------------

I made a similar patch against 4.0.3 that we are testing out now tries to improve the attached patch(new patch attached):

- Properly signal that lock was removed from map using notifyAll
- Replaces the map with a set, and simplify/fix logic in the check. I think its a bit easier to understand at least.

It also:
- Adds registerAsParallelCapable
- Makes bundleclassloader and bundleclassloader5 static (I just used intellij's 'make static' to get this done)

Still unresolved:
- Handling interruptedexception.

Let me know if you can review it, or if I should try produce a patch against trunk. Btw, if you have any stress tests that can easily reproduce the deadlock issues, that would also be very helpful.

Thanks
