Embedded nstest shows ERROR 40001: A lock could not be obtained due to a
deadlock, in nstest
---------------------------------------------------------------------------------------------
Key: DERBY-5430
URL: https://issues.apache.org/jira/browse/DERBY-5430
Project: Derby
Issue Type: Bug
Affects Versions: 10.8.2.1
Environment: Windows XP, Suse Linux, NsTest Embedded, ibm 1.6 SR9 FP1.
Reporter: Myrna van Lunteren
When running the nstest system test with Embedded with the 10.8.2.1 release
candidate, or a build sync-ed to the top of the 10.8 tree (at level: version:
10.8.2.2 - (1174879M) - the M is to add checks (only do if not null) to number
of PreparedStatement.close() calls), I now see a number of deadlock errors if I
capture the output to a file.
The test run with network server did not show this problem.
10.7.1.1 and 10.8.1.2 did not show this problem.
There's nothing in derby.log, but this is an example of the error to the
console as captured in a file:
Thread 37 is now running
