Subject svn commit: r1559151 - in /commons/proper/scxml/trunk/src/test/java/org/apache/commons/scxml2/env/groovy: GroovyClosureTest.java groovy-closure.xml

New Revision: 1559151

URL: http://svn.apache.org/r1559151
Log:
SCXML-186: Groovy Expression evaluator support
- Simple test to validate and demonstrate using Groovy closures *is* possible although not
recommended to be used.
  Using Groovy closures for SCXML is strongly discouraged because of the limitations
  (like NOT serializable) and serious memory/performance overhead they may cause.

  Better use the initial script feature as an script base and def(ine) methods which provides
same/similar capabilities
  without the costs of closures. As an example, see: serializable-initial-base-script.xml
