Comment 2 Ondrej Vrabec 2009-10-09 12:32:31 UTC 
Loading a class from the same jar (org-netbeans-modules-bugtracking.jar) fails. 
TaskListProvider is from org.netbeans.modules.bugtracking.tasklist package in IssueTracking module.
BugtrackingOwnerSupport and BugtrackingOwnerSupport$DefaultImpl are from org.netbeans.modules.bugtracking.util package
in the same module.

I spoke to the reporter, it happened to him just once, the next time he started IDE, everything went fine (so maybe a
random failure).
Please evaluate

Root cause looks to be:

java.lang.InterruptedException
	at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquireSharedInterruptibly(AbstractQueuedSynchronizer.java:1215)
	at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:218)
	at java.util.concurrent.FutureTask.get(FutureTask.java:83)
	at org.netbeans.JarClassLoader$JarSource.callGet(JarClassLoader.java:589)

	at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:224)

Might be other cache-related problems; note

WARNING [org.netbeans.core.projects.cache]: layer
jar:file:/home/uadmin/NetBeansProjects/cdev/nbbuild/netbeans/ide12/modules/org-netbeans-modules-options-editor.jar!/META-INF/generated-layer.xml
contains duplicate attributes displayName for Projects/org-netbeans-modules-maven/Customizer/Formatting

whereas in my build tree

options.editor/build/classes/META-INF/generated-layer.xml

has just

                <folder name="Formatting">
                    <attr bundlevalue="org.netbeans.modules.options.indentation.Bundle#LBL_CategoryFormatting"
name="displayName"/>
                    <attr intvalue="1000" name="position"/>
                    <file name="Self.instance">
                        <attr
methodvalue="org.netbeans.modules.options.indentation.FormattingCustomizerPanel.createCategoryProviderForAll"
name="instanceCreate"/>
                        <attr intvalue="0" name="position"/>
                    </file>
                </folder>

which has no duplication.
