Subject [jira] Commented: (JDO-324) Derby "ERROR 40XL1" in multithreaded test "RefreshAllNoParameterSideEffects"
Date Wed, 01 Mar 2006 19:23:54 GMT
    [ http://issues.apache.org/jira/browse/JDO-324?page=comments#action_12368341 ] 

Craig Russell commented on JDO-324:
-----------------------------------

I looked at the test, and it appears that the test is not correct. It is too complex for what
it's testing, and doesn't even test what the assertion says.

For now, I propose adding the three test cases to the exclude list and fix this later.

> When using latest JPOX nightly (01-Mar-2006 04:21), I get a "ERROR 40XL1: A lock could
not be obtained within the time requested" Derby error (see next attachment for log file).
This happens while running RefreshAllNoParameterSideEffects, which is multithreaded, and it
happens for both threads.
> This is with Windows XP SP2 and JDK 1.4.2_09 on a dual core machine. Maybe the fact that
it is dual core leads to different timing than single core?
