> I came across a query that failed with a NullPointerException (insane jars) or an assert
failure (sane jars) when a PreparedStatement was re-executed after a lock timeout. I'm able
to reproduce this on 10.3.1.4 and later. 10.2.2.0 and earlier don't fail. Another fallout
from DERBY-827? I've also seen other manifestations of the problem, apparently depending on
the actual rows in the tables, including "No current connection" and "The heap container with
container id Container(0, 1120) is closed".
