Dear mailing list readers,

I’m interested in measuring the time needed by Henshin to execute a transformation (see attached cdrefinement.henshin) on a given xmi model ( size10.xmi conforming to CD.ecore). The transformation works great when running through eclipse but unfortunately I can’t see any log of the time it took to be computed.
I thus tried my luck in developing a small java application running the transformation and printing out the time taken and can’t get rid of a NullPointerException...
Here is the stacktrace: (note that I simply reused the code given in the henshin interpreter web page)

Exception in thread "main" java.lang.NullPointerException

                at org.eclipse.emf.ecore.impl.EClassImpl.getFeatureID(EClassImpl.java:1500)

                at org.eclipse.emf.ecore.impl.DynamicEObjectImpl.eDerivedStructuralFeatureID(DynamicEObjectImpl.java:218)

                at Interpreter.interpret(Interpreter.java:80)

                at Main.main(Main.java:38)

Do you have any idea what causes this error ?

Also, is there a way to get the time taken by henshin to execute a transformation directly in eclipse ( without having to program anything )

Cheers,
Loïc
