[jira] [Created] (DERBY-5390) NPE in BasicDatabase.stop in
replication slave mode (dd.clearSequenceCaches)
NPE in BasicDatabase.stop in replication slave mode (dd.clearSequenceCaches)
----------------------------------------------------------------------------
Key: DERBY-5390
URL: https://issues.apache.org/jira/browse/DERBY-5390
Project: Derby
Issue Type: Bug
Affects Versions: 10.8.1.6, 10.9.0.0
Reporter: Kristian Waagan
Assignee: Kristian Waagan
Priority: Minor
To reproduce, set up a replication pair and then stop the master (I used "stopMaster=true").
>From derby.log on the slave:
Replication slave role was stopped for database 'replicDB'.
java.lang.NullPointerException

The reason is that there is no data dictionary available when the database is in replication slave mode.
Note that the exception is caught and simply printed to derby.log.

Kristian Waagan commented on DERBY-5390:
----------------------------------------
The fix here is simple: check if the data dictionary is available.
I'm wonder why Throwable is caught though - why not catch only StandardException?
