Kristian Waagan updated DERBY-3379:
-----------------------------------

    Attachment: derby-3379-1a-enforce_no_chaining.stat
                derby-3379-1a-enforce_no_chaining.diff

'derby-3379-1a-enforce_no_chaining.diff' is an attempt to fix both the NPE and the bug hiding underneath.

The basic strategy is to make sure the last DSS has the chaining bits set to no chaining when endWriteChain is called and the data is flushed (sent over the wire).

I am not sure if this is the best approach, but it fixes the bug. I have run suites.All successfully with an earlier version of the patch, and I'm now running both derbyall and suites.All with this version to confirm that nothing breaks.

Patch is ready for review, but not for commit. There is an unnecessary method rename in there that will go into a separate commit.

> This is the client version of bug DERBY-2142.  It can be reproduced by enabling the test, DataSourceTest.testPooledReuseOnClose() for client. I am opening a new issue for client as the embedded fix was backported to 10.1 and I am guessing the client fix won't be backported that far.  Better to keep it as  a separate issue.
