Description
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.
