[jira] Resolved: (DERBY-2547) possible NullPointerException in
client/am/ProductLevel
Posted by "Myrna van Lunteren (JIRA)" <ji...@apache.org>.

Myrna van Lunteren resolved DERBY-2547.
---------------------------------------
Resolution: Duplicate
I'm marking this one as a duplicate.
I did a simple check by adding a println to the identified line in the code, then ran DataSourceTest, and there was no situation where there was a null productID - until I added testJira95ds in to the client run.
So, I definitely think it's a dup of DERBY-3407 / DERBY-2498 - and those have something of a repro described.

----------------------------------------
I agree with Dan, some more investigation should be done.
You might get some pointers from looking at the relevant code in the embedded driver, *assuming* this bug is the same as the one I reported earlier today.

---------------------------------------
What do you think should be the value of versionLevel_ if productID is NULL.

-------------------------------------------
I cannot remember even what fixture I was stepping through when I saw this, nor a do I have a repro. I do remember specifically that things seemed to go on successfully *after* the NPE.

Daniel John Debrunner commented on DERBY-2547:
----------------------------------------------
Is productID being null here correct? With an NPE it's best to first find out why the reference is null, rather than just handling the case when it is null not to throw an NPE.

----------------------------------------
Seems I just created a possible duplicate for this issue (DERBY-3407).
Don't know if it is the same bug, but there is a vague description on how to reproduce the NPE there.

Could you please relate as to how did this NPE occur so that I can reproduce it on my system.
