A serious problem for JDev too.
Comment 2 Tomas Pavek 2013-01-02 17:08:35 UTC 
In JDev the messages look like:

Jan 1, 2013 7:22:10 AM org.openide.util.RequestProcessor isNotHuge

Comment 3 Jaroslav Tulach 2013-01-03 14:15:02 UTC 
In case of Netigso and FolderChildren the huge amount of runnables is appropriate. They contain different data - in one case for different messages to print, in the other for different folders. Counting number of Runnable classes does not make much sense in these cases.

As I am unable to differentiate between these cases and the problematic case that initiated by investigation of the issue 223865 I suggest to backout: 1e328a630a9f
