[teiid-issues] [JBoss JIRA] Resolved: (TEIID-1110) NPE Connecting to a Teiid DataSource (XA) as Anonymous User

[Ramesh Reddy (JIRA)]

     [ https://jira.jboss.org/browse/TEIID-1110?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ramesh Reddy resolved TEIID-1110.
---------------------------------

    Resolution: Done


When the data source is created with no credentials,  user name is assumed as 'anony,ous' with password as null. The code was not properly checking for the password as null; thus NPE. Fixed code to avoid the NPE in this situation.
