----------------------------------
Summary: Exception when JMS source tries to connect to a Weblogic
server without authentication
Key: FLUME-2976
URL: https://issues.apache.org/jira/browse/FLUME-2976
Project: Flume
Issue Type: Bug
Components: Sinks+Sources
Affects Versions: v1.6.0
Reporter: Denes Arvay
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.

Changing the above mentioned line to {{Optional.absent()}} fixes the issue.
[~brocknoland]: Is there any specific reason for setting the password to
{{Optional("")}} when there is no {{passwordFile}} set?
