> NullPointerException in newBrokeredStatement in app server environment
> ----------------------------------------------------------------------
>
> Key: DERBY-3513
> URL: https://issues.apache.org/jira/browse/DERBY-3513
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.1.3.2
> Environment: Java Version: 1.5.0
> Java Vendor: IBM Corporation
> OS name: Linux
> OS architecture: x86
> OS version: 2.6.9-55.ELsmp
> Reporter: Kathey Marsden
> Attachments: derby-3513_diff.txt

> User reports in an app server environment an intermittent
> NullPointerException
> with the 10.1 trace:
> R java.lang.NullPointerException
> org.apache.derby.iapi.jdbc.BrokeredConnection.newBrokeredStatement(BrokeredConnection.java:448)
>
> ...org.apache.derby.jdbc.XAStatementControl.<init>(XAStatementControl.java:62)
>
> ...org.apache.derby.jdbc.EmbedXAConnection.wrapStatement(EmbedXAConnection.java:827)
>
> org.apache.derby.iapi.jdbc.BrokeredConnection.createStatement(BrokeredConnection.java:296)
> [snip user trace]
> The code at line 448 is simply:
> return new BrokeredStatement(statementControl, getJDBCLevel());
> so not much room for an NPE there. I added println statements to identify
> the state values and where the NPE is actually occurring but that seemed to
> make the
> problem go away. It may be a JIT issue.
> I gave them the fix for DERBY-2142 and that did not correct the problem.
