Log Message:
-----------
Fixing a bug in CPS VM about how it handles an exception in sync body.
See the previous commit for the test case that reproduces this problem.
Any exception aside from CpsCallableInvocation is a sign that the
execution has completed abnormally and synchronously. So this code pass
should have close parallel to the normal case that immediately follows
the 'params.body.getBody(currentThread).call()' invocation, yet the
thread association is missing from the failure case.
CpsBodyExecution.onSuccess/onFailure also assumes that they run in
CPS VM thread to be able to grow the flow node graph, as can be seen
in their use of CpsThread.current(). In the typical case where the body
being invoked is also CPS code, this assumption correctly holds as these
callbacks as invoked as Continuation while running CPS thread code, but
if it executes synchronously, this assumption does not hold, as the call
stack originates in `ThreadTask.eval(this)` that's outside the code
that sets the CpsThread.current() return value.
ThreadTask.eval() always operate in the context of single CpsThread,
it seems reasonable to run this code whiel CpsThread.current() is still
set.
(bug that motivated this change, from the parent of this commit)
------------------------------
When the body of a step is synchronous and explodes, the failure should
be recorded and the pipeline job should move on.
But instead, this hangs because CpsBodyExecution has a bug in how it
handles this case. It tries to launch the body (in this case the
'bodyBlock' method) in a separate CPS thread, and puts the parent CPS
thread on hold. Yet when the child CPS thread ends with an exception, it
fails to record this result correctly, and it gets into the eternal
sleep in which the parent CPS thread expects to be notified of the
outcome of the child CPS thread, which never arrives.
