Description

I have the following program

class Test {
  Test(String x) {}
  class Foo extends Test {}

  public static void main(String[] args) {
    Test x = new Test("");
    Test.Foo y = x.new Foo();
  }
} 

Actual behavior

The code compiles, but there's a runtime error

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0
    at Test$Foo.<init>(test.groovy)
    at Test.main(test.groovy:8) 

Expected behavior

The code should have been rejected.
