Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.4
Environment: windows xp sp 3
Reporter: Doug Bradbury

Priority: Minor
Attachments: monitor_bug.zip

spec:1:
I expect that in a processor starved situation that this spec might fail, but I
don't think that any situation should cause the
MonitorMixin::ConditionVariable::Timeout should ever bubble up to the caller of
wait.
