ContextAction.isEnabled() is too slow. Not sure if it's a problem in the Actions module or just some specific Action implementation is wrong.
Please feel free to reassign, thanks.
Comment 3 Jaroslav Tulach 2012-10-24 08:13:50 UTC 
One call to 
org.openide.explorer.ExplorerManager$1AtomicSetSelectedNodes.fire()
yields 661 calls to
org.openide.awt.ContextManager$LSet.resultChanged() 19 592 ms	661 times!

We don't have that many visible actions. Some non-visible has to be leaking and remain around. But everything is generic, I have no way to find out from the snapshot what module registered such nasty action.


ergonomics#ed4d6c4b0fcc adds more logging - whoever wants us to help analyse the problem, needs to run with:

-J-Dorg.openide.awt.GeneralAction.level=FINE
