             Summary: BufferManager reserved thread local can keep buffermanager references alive
                 Key: TEIID-2359
                 URL: https://issues.jboss.org/browse/TEIID-2359
             Project: Teiid
          Issue Type: Feature Request
          Components: Query Engine
    Affects Versions: 8.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins


The most common implementation of ThreadLocal holds does not garbarge collect ThreadLocal values when the ThreadLocal goes out of scope - only when the Thread stops.  Thus the BufferManager reserved threadlocal being a non-static inner class is inadvertently keeping a reference alive. 

Marked as starting with Teiid 8.0 as selective Teiid restarts (which is how multiple instances are introduced) are not performed in the 7.x series.
