Description Jaroslav Tulach 2008-10-29 09:48:25 UTC 
In case of "inversion of control" waiting, one could get the request processor into a starvation. This happened quite 
often in datasystems tests, where modifications to disk happen in parael with scheduling and waiting for various 
tasks.

Comment 3 Jesse Glick 2008-10-29 16:29:36 UTC 
How old is this? Reported against 7.0 but I presume a (potential) problem for much longer.
Comment 4 Jaroslav Tulach 2008-10-29 17:56:14 UTC 
The code is there since 3.4, at least, maybe it is there even for longer amount of time.
Comment 5 Quality Engineering 2008-10-30 04:57:10 UTC 
Integrated into 'main-golden', will be available in build *200810300201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
