Kathey Marsden commented on DERBY-4053:
---------------------------------------

Hi Mamta,

I took a look at DERBY4053_patch1_diff_July092009.txt.  On visual inspection it seems like
it should do what we want.
There is an import of BrokeredConnectionControl in EmbedConnection which should be removed.
 

In your mail to derby-dev, you said "Despite the
change, I still get the hang. "  Do you still get the InvalidReply? If you put the try/catch
block around the shutdown operations, do you still see an exception?

I did some grepping on the tests in jdbc4 and I think you are right that they only use local
transactions.

> Running suites.All with IBM 1.5  on 10.5.0.0 alpha - (743198)  I got a hang in the test
run.  The last test to run successfully was xtestNestedSavepoints, but I am not sure exactly
what test caused  the hang.  I took a thread dump which I will attach, which showed network
server up and running but no ClientThread and a ping attempt blocked.
> This hang is very similar to the hang that was seen after the fix attempts for DERBY-1465
but that change was backed out so it is not related to that change.   It could be that the
change for DERBY-1465 just made this highly intermittent problem more likely.
