bumped into a compiler NPE when replaced lambda with an anonymous class

[Maurizio Cimadamore]

This will do:

class CompilerError {

      public static void main(String[] args) {
          SAM s = ()-> { SAM s2 = ()->{ new Object() { }; }; };
      }

      interface SAM {
          void m();
      }
}


 From the stack trace it looks like the the translator is missing that 
the anon class occurs in a static context and therefore no 'enclosing 
this' should be added.
