>             Project: Derby
>          Issue Type: Bug
>         Environment: windows (7, 2008), IBM jvm 1.6 SR15, 1.7 SR6
>            Reporter: Myrna van Lunteren
>            Priority: Minor

> 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.
