Possible bug in CachedPage class

Has anyone else seen this issue in the org.apache.derby.impl.store.raw.data.CachedPage class?  In the writePage() method, there's a test of the myContainer reference to ensure it's not null (line 771), however in the else block, myContainer is dereferenced (line 836), where a NullPointerException is guaranteed to be thrown.  This is in Derby 3.1.4.

I searched through JIRA, but didn't find anything on this.  If anyone else can confirm that this is an issue, I'll put in a report on it.

Thanks,
Jason

Hi Jason,

It sure looks like a bug, so it would be great if you could file a
report in JIRA. Thanks for letting us know!
