Description

If no userName and passwordFile is set for the JMS source it sets the password to Optional("") (see: https://github.com/apache/flume/blob/trunk/flume-ng-sources/flume-jms-source/src/main/java/org/apache/flume/source/jms/JMSSource.java#L127)
This leads to an exception in the weblogic jndi context implementation when trying to connect to a weblogic jms server.

java.lang.IllegalArgumentException: The 'java.naming.security.principal' property has not been specified
	at weblogic.jndi.Environment.getSecurityUser(Environment.java:562)
	at weblogic.jndi.WLInitialContextFactoryDelegate.pushSubject(WLInitialContextFactoryDelegate.java:665)

	at org.apache.flume.source.jms.JMSSource.doConfigure(JMSSource.java:223)

Changing the above mentioned line to Optional.absent() fixes the issue.

Brock Noland: Is there any specific reason for setting the password to Optional("") when there is no passwordFile set?
