Subject [jira] Updated: (DERBY-4676) NullPointerException on SELECT on INNER JOIN
Date Wed, 07 Jul 2010 00:43:50 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4676?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mamta A. Satoor updated DERBY-4676:
-----------------------------------

    Attachment: derbyall_diff.txt
                derbyall.sum
                derbyall_fail.txt

When I ran derbyall after the merge on 10.5 codeline, I saw a NPE for
derbyall/derbynetclientmats/derbynetmats.fail:derbynet/dblook_test_net.java

Not sure if it is indeed that test ran into NPE because I don't see one under that actual
test directory. The derbyall.sum file has following
*** End:   dblook_test_net jdk1.6.0 DerbyNetClient derbynetmats:derbynetmats 2010-07-06 16:34:52

When I look directly under C:\p4clients\svn10.5\client1\10.5\systest\out142\derbyall\derbynetclientmats\DerbyNetClient\derbynetmats\derbynetmats,
I don't see NPE in the files created for dblook_test_net

I have attached the top level derbyall suite report files for reference.

>             Project: Derby
>          Issue Type: Bug
>    Affects Versions: 10.5.3.0, 10.6.1.0
>         Environment: Windows XP, same problem occurred using Apache Derby 10.5.3.0 and
still with the newly release 10.6.1.0 version.   
> For completeness, also noting using c3p0 0.9.1-pre10 and hibernate 3.0.5.   Attempted
trying later versions of both (c3p0 and hibernate) to see if this resulted in a workaround,
but had no success.

> Running into a NullPointerException error in the Apache Derby database over multiple
versions of the derby jars.  From testing, this issue intermittently occurs during moderate
load test scenarios, but has never occurred in production.   This is using Derby as embedded
and always occurs on the same statement as shown below and in the attachment.   Following
the error, hibernate throws an exception which results in the code attempting to rollback
the transaction.  The rollback fails as the NullPointerException appears to kill the connection.
