Environment:

  • Eclipse IDE for Java Developers 4.6.3.20170314-1500
  • Groovy-Eclipse Feature 2.9.2.xx-201706120159-e46
  • JDT Core patch for Groovy-Eclipse plugin on Eclipse 4.6 2.9.2.xx-201706120159-e46

I changed a function

def static myFunc(...)

to

static Map<String, MyObject> myFunc(...)

And now I'm looking at the following stack trace
