Evaluate operations defined via OCLinEcore in the interactive console yields OCLinvalid [message #733983]

Hi,

I
- downloaded a fresh indigo

- replayed the tutorial help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.ocl.doc%2Fhelp%2FTutorials.html until "Helper Features and Operations" (execute isAvailable() in the OCL interactive console).

- got the result OCLInvalid as indicated in the screenshot below.

The stacktrace in the errorlog is:

java.lang.NullPointerException
at org.eclipse.ocl.ecore.EcoreEvaluationEnvironment.getJavaMethodFor(EcoreEvaluationEnvironment.java:225)
at org.eclipse.ocl.ecore.EcoreEvaluationEnvironment.getJavaMethodFor(EcoreEvaluationEnvironment.java:1)

Hi

See

https://bugs.eclipse.org/bugs/show_bug.cgi?id=360072

for discussion of problem of using Indigo Pivot/Xtext delegates in the non-Xtext console.
