With the patch, getDescriptorViaIndexMinion() sometimes uses read uncommitted isolation level, but still it uses next() + fetch() instead of fetchNext(). Do you think this could cause any problems? > StackOverflowException in deadlock trace > ---------------------------------------- > > Key: DERBY-3678 > URL: https://issues.apache.org/jira/browse/DERBY-3678 > Project: Derby > Issue Type: Bug > Affects Versions: 10.3.2.1 > Environment: (this is actually in version 10.3.2.2) > MacOS 10, JDK 1.6 > Reporter: geoff hendrey > Assignee: Dag H.
