Subject [jira] [Commented] (DERBY-6833) NPE in IndexRowGenerator.getExecutionFactory()
Date Mon, 21 Sep 2015 11:52:04 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14900548#comment-14900548
] 

Edward Howe commented on DERBY-6833:
------------------------------------

We had the crash occur again, with the following derby log output.  (We are writing the derby
log to our application log by setting derby.stream.error.method).  derby.stream.error.logSeverityLevel
is set to 20000.

> Derby crashed with the following stack trace while running our application's integration
tests.  This is the first time I've seen this, and cannot reproduce it.  It happened during
our application's startup.  The embedded database had been opened by this point, and some
initial queries had been executed.
