[henshin-dev] RuntimeException related to Nashorn

[Vlad Acretoaie <rvac@xxxxxx>]

Hi,

 

I just came across a slightly unusual exception occurring in the following scenario: in a UML model, I would like to preserve a Class named “HTTPConnection” (the name is not relevant, I tried changing it). However, as soon as I add the “name” Attribute to the Henshin node representing the Class, the transformation fails with the following exception:

 

Exception in thread "main" java.lang.RuntimeException: ReferenceError: "HTTPConnection" is not defined in nashorn:mozilla_compat.js at line number 67

                at remove_attribute.RemoveAttribute.main(RemoveAttribute.java:40)

 

The transformation does nothing else than preserve that Class (it is a trivial example I constructed for debugging purposes). I am attaching the Henshin file, the source model, and the Java code I’m using to execute the transformation, in case they help.

 

Does anyone have some ideas as to what may be causing this?

 

Cheers,

Vlad
