      Description

      Compiling this code:

      public class X {
          public class Y {
          }
          Y foo() {
              Y goo() {
                  return new Y();
              }
              return goo();
          }
          public static void main(String [] args) {
              Y y = new X().foo();
              System.out.println("y = " + y);
          }
      }

      results in:

      java.lang.ClassCastException: class com.sun.tools.javac.comp.LambdaToMethod$LambdaAnalyzerPreprocessor$LocalMethodTranslationContext cannot be cast to class com.sun.tools.javac.comp.LambdaToMethod$LambdaAnalyzerPreprocessor$LambdaTranslationContext (com.sun.tools.javac.comp.LambdaToMethod$LambdaAnalyzerPreprocessor$LocalMethodTranslationContext and com.sun.tools.javac.comp.LambdaToMethod$LambdaAnalyzerPreprocessor$LambdaTranslationContext are in module jdk.compiler of loader 'app')
