[jira] [Commented] (QPID-3743) [Java Broker] Remove catching of
Exception during metadata retrieval in BDB store
Posted by "Robbie Gemmell (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/QPID-3743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13210162#comment-13210162 ]
Robbie Gemmell commented on QPID-3743:
--------------------------------------
Updated title to reflect new scope. It has not been possible to reproduce the NPE seen above, and Rob is unsure it was on a clean trunk following some changes to persistence etc. What is clear though is that the NPE should only be possible if an exception was caught and null returned, where really the exception should have been thrown. This JIRA will now be used to make that change.
