Subject [jira] Updated: (DERBY-4306) NullPointerException in JMXManagementService.unregisterMBean when running jdbcapi._Suite
Date Tue, 21 Jul 2009 21:15:14 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4306?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden updated DERBY-4306:
----------------------------------

    Attachment: ReproDerby4306.java

Mamta asked me to post a stand-alone reproduction for this issue. Attached is ReproDerby4306
which does I think get the  JMX NPE but it is masked by a problem with the new DERBY-4304
error handling.  There is no error to the console but  we never see the shutdown complete
message and in derby.log I see:
An exception was thrown during network server startup. null
java.lang.reflect.InvocationTargetException
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

	at java.lang.Thread.run(Thread.java:735)
Caused by: java.lang.NullPointerException

	at org.apache.derby.impl.drda.NetworkServerControlImpl.blockingStart(NetworkServerControlImpl.java:895)
	... 6 more

Should I file a separate bug for the NPE introduced by DERBY-4304?
