> 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?
