[teiid-issues] [JBoss JIRA] (TEIID-3057) Kerberos ODBC connection on Teiid 8.8.0

[Ramesh Reddy (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-3057?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ramesh Reddy resolved TEIID-3057.
---------------------------------

           Labels: Alpha1  (was: )
    Fix Version/s: 8.7.1
                   8.9
       Resolution: Done


Added null check to avoid the NPE. When delegation is in effect it will have the non-null object. IMO, the confusion raised from LogonResult properties generic map and Hastable usage in the ODBC where it does not allow null inserts.
