Description

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.
