Kathey Marsden commented on DERBY-1108:
---------------------------------------
Yes. It is so much harder when the problem is that you are *not* throwing the
error. You have to trace back through the code and figure out what return
value was not the value expected. My line numbers don't match up to yours
but presumably verifyAllHeldResultSetsAreClosed() is returning false instead of
the expected true value.
If you look at verifyAllHeldResultSetsAreClosed() you can see it is relying on
this gc:
// There may be open ResultSet's that are yet to be garbage collected
// let's try and force these out rather than throw an error
System.gc();
System.runFinalization();
That would be my first guess as to the cause of the trouble. Probably this JVM
is not garbage collecting the open resultsets in this case.
In your test case has the resultSet been explicitly closed or was it left open
with the expectation of garbage collection before the setTransaction isolation
call?
