             Summary: Race condition in MVELDialectRuntimeData.getParserConfiguration
                 Key: DROOLS-1359
                 URL: https://issues.jboss.org/browse/DROOLS-1359
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 6.5.0.Final, 5.5.0.Final
            Reporter: Anuj Shah
            Assignee: Mario Fusco


MVELDialectRuntimeData attempts to hold a lazy loaded ParserConfiguration. The getParserConfiguration method sets this to a new configuration object and then sets the imports on the configuration. Between these two steps another thread could retrieve the stale configuration and use it. This could result in a number of exceptions in compilation.

A simple fix is to delay assignment of new ParserConfiguration until after the imports are set.
