Problem Description: -------------------- I'm trying to work on making one of our long running tasks cancellable. I have hit a problem with the netbeans classloader code. If the current Thread is interrupted before (or while) JarClassLoader is used (in our case because we're using the bean Introspector on some classes) then it will no longer be interrupted when JarClassLoader has finished. Error-Stack Obtained / Diagnostic Analysis: ------------------------------------------- The cause would seem to be a catch( InterruptedException ) in org.netbeans.JarClassLoader which doesn't re-throw, and doesn't ensure Thread.currentThread().interrupt(). I found this one example, but I'm guessing there may be others in the netbeans classloader code. The code base should be checked to ensure that InterruptedException is dealt with properly (i.e. at least call Thread.currentThread.interrupt() if not handling it. http://www.ibm.com/developerworks/java/library/j-jtp05236/index.html
I see one method that deals with interrupts in JarClassLoader. Here is the attempt to propagate the state: changeset: http://hg.netbeans.org/ergonomics/rev/41bd41fea39e tag: tip parent: 35b2705af4c1 user: Jaroslav Tulach <jtulach@netbeans.org> date: Mon Mar 31 10:01:19 2014 +0200 summary: #241444: Propagate interrupted state
