             Summary: GitRefresh thread consumes 100% cpu after few mins of NetBeans usage
                 Key: NETBEANS-5870
                 URL: https://issues.apache.org/jira/browse/NETBEANS-5870

          Issue Type: Bug

    Affects Versions: Next

after a while of using NetBeans, GitRefresh thread starts to eat up the whole cpu. the trigger for this is saving a file in editor. in the beginning the issue does not occur, but only after few mins NetBeans becomes non-responsive and cpu load is 100%. killing NetBeans is the only option then. it's hard to code anything when you have only few mins before you have to kill it.

here's screenshot from VisualVM showing the thread eating up the cpu:

i'm also attaching snapshot from VisualVM monitoring.
