Rick Hillegas created DERBY-6496:
------------------------------------

             Summary: Optional tool registration may fail because the 
CompilerContext is not always available at execution time.
                 Key: DERBY-6496
                 URL: https://issues.apache.org/jira/browse/DERBY-6496
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.11.0.0
            Reporter: Rick Hillegas


For reasons which elude me, the CompilerContext is sometimes available at 
execution time and sometimes not. When the CompilerContext is not available at 
execution time, optional tool loading fails on an NPE:
