1 == new Object() throws ClassCastException

    Details

    • Type: Bug
    • Status: Closed
    • Priority: Critical
    • Resolution: Fixed
    • Affects Version/s: 1.7.0
    • Fix Version/s: 1.6.8, 1.7.1, 1.8-beta-1
    • Component/s: None
    • Labels:
      None
    • Environment:
      tested for 1.7.0 and 1.6.0

      Description

      Example 1:

      assertFalse(new Object() == 1) // this is ok
      assertFalse(1 == new Object()) // this throws a ClassCastException, because Groovy redirects the call to java.lang.Integer.compareTo(Integer i)

      Example 2:

      enum MyEnum

      { A, B, C }

      assertFalse(new Object() == MyEnum.A) // this is ok
      assertFalse(MyEnum.A == new Object()) // this throws a ClassCastException, because Groovy redirects the call to java.lang.Enum.compareTo(E e) where E extends java.lang.Enum<E>
