Description

I have a class with the following code:

class UnitGroupMap {
  ...
  static Map suffixPriority = ['a' : 10, 'b' : 20]
  ...
  enum UnitGroup {
    SAMPLE("foo"),
    ...
    UnitGroup(String name) {
      ...
      suffixPriority[name] = priority
      ...
    }
  ...
  }
  ...
}

The compiler does not complain, STS doesn't complain, but at runtime, there's an exception that "suffixPriority" is not a member of UnitGroupMap.UnitGroup.

To make this code work, I have to precede the suffixPriority reference with the class name: UnitGroupMap.suffixPriority

Either this should work as written, or the compiler should generate an error or at least a warning. However, STS at least highlights suffixPriority in italics as though it can and does see the field should be coming from the parent class, UnitGroupMap.
