Subject [jira] Created: (DERBY-3513) NullPointerException in newBrokeredStatement in app server environment
Date Fri, 07 Mar 2008 17:01:51 GMT
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:
         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

User reports in an app server environment an intermittent  NullPointerException
with the 10.1 trace:

 R java.lang.NullPointerException
,,, [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.
