When creating syntactically invalid stratego constructors a nullpointer exception rises.

Minimal example:

module test
signature
  sorts A
  construtors
    Foo : A -> A -> A

The stacktrace below is created with an older version of spoofax. In the current version (1.2.0.0-s41460) no stacktrace is shown.

    java.lang.NullPointerException
