Dag H. Wanvik commented on DERBY-6549:
--------------------------------------
Thanks, Myrna. I looked at that download bundle, but it's a lot of legalese
(IANAL) in the licence and I am not sure I can download it since it wasn't
clear to me if I could legally use it while working for Oracle... it would be
good sometimes to be able to use the IBM JDKs to flush out bugs that don't show
up in the Oracle ones..

> Key: DERBY-6549
> URL: https://issues.apache.org/jira/browse/DERBY-6549
> Project: Derby
> Issue Type: Bug
> Environment: windows (7, 2008), IBM jvm 1.6 SR15, 1.7 SR6
> Reporter: Myrna van Lunteren
> Priority: Minor
> Attachments: XALongReproD6549.java, XAShortReproD6549.java
>
>
> This error occassionally showed up in the XATest.testDerby966 before a
> rollback() was placed before the close().
> For some reason, Derby client received an extra, empty, SQLCARD (Codepoint
> 2408).
> This never happened with the Oracle JVMs, but has been reproduced with ibm
> 1.6 and 1.7 JVMs. Thus, it might be a JVM issue.
> However, it is not a JVM issue, and does not appear to be a gc issue or
> memory issue.
> Also, the frequency of the occurrences is higher with trunk (10.11) than with
> 10.10 or 10.9, thus, it is still possible there is a Derby component.
> See for more info regarding the original test failure DERBY-6248.
