Description Vladimir Voskresensky 2010-05-12 15:47:29 UTC 
Created attachment 98878 [details]
thread dump of frozen IDE

During "checking for external changes" in Suspended mode I have called Find Usages which displayed dialog but all buttons were inactive except cancel. After some waiting I pressed Cancel in dialog. "checking for external changes" was still in Suspended mode. I pressed cancel (x) in progress bar of this task and confirmed cancellation, but not disabling.
After that IDE is frozen
Comment 1 Stanislav Aubrecht 2010-05-13 09:29:17 UTC 
(perhaps a duplicate of an older bug?)
Comment 2 Jaroslav Tulach 2010-05-13 13:45:27 UTC 
The question is whether:

org.netbeans.modules.masterfs.filebasedfs.children.ChildrenSupport.refresh(ChildrenSupport.java:140)
        - locked <0x9f0b2bf0> (a org.netbeans.modules.masterfs.filebasedfs.fileobjects.FolderObj$FolderChildrenCache)
org.netbeans.modules.masterfs.filebasedfs.fileobjects.FolderObj$FolderChildrenCache.refresh(FolderObj.java:561)

also means that ChildrenCache.mutex is being held.
Comment 3 Jaroslav Tulach 2010-05-13 13:48:19 UTC 
As there is:
        mutexPrivileged.enterWriteAccess();
        try {
            oldChildren = new HashSet<FileNaming>(cache.getCachedChildren());
            refreshResult = cache.refresh();
        } finally {
            mutexPrivileged.exitWriteAccess();
        }

in FolderObj. I assume this is duplicate.
