Description Chris Moller 2006-10-12 18:33:42 UTC 
testDetachExec(frysk.proc.TestTaskObserverDetach)java.lang.RuntimeException:
Whoa!

happened 2 or 3 times from installed funit, but hasn't repeated since.  appears
to be intermittant.
Comment 1 Chris Moller 2006-10-12 21:17:18 UTC 
There are four cases in this test:

testDetachFork
testDetachClone
testDetachExec
testDetachSignal

of which testDetachExec fails with the error above.  If the testDetachFork case
is removed, the test passes.

The proximate casuse of the failure is in
frysk/proc/TaskState.java:handleStoppedEvent():

Collection pendingObservations = task.pendingObservations;
          if (pendingObservations.isEmpty())
            throw new RuntimeException("Whoa!");

from a backtrace of 

at frysk.proc.TaskState$Running.handleStoppedEvent(TestRunner)                 
at frysk.proc.Task.processStoppedEvent(TestRunner)

Guess du jour, it's another tearDown problem--I'll refinne that guess tomorrow.
