[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2415?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-2415.
-----------------------------------

    Resolution: Done


Ensured that the properties object is thread-safe and made all mutable fields volatile to ensure up-to-date reads.

> Some metadata values can be changed at runtime, such as transformations, stats, and properties.  In the case of transformations and stats an exception won't occur, but the most up-to-date value may not be read by other threads.  Changing the properties could cause an exception as the map changes are not concurrency safe - similar to TEIID-2342
