[teiid-issues] [JBoss JIRA] (TEIID-5807) Multiple levels vdb-importing results in error

[Steven Hawkins (Jira)]

     [ https://issues.jboss.org/browse/TEIID-5807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-5807.
-----------------------------------
    Fix Version/s: 12.3
                   12.1.2
                   12.2.2
       Resolution: Done


Corrected to use a hashset instead.  

In general the notion of classpath search order with imported vdbs is a little ill-defined - should importing vdb libs override lower ones?  Should there be an error on conflict, etc.
