31 // The check_final_method_override function in ClassfileParser uses an |
|
32 // accessability check to see if the subclass method overrides a same-named |
|
33 // superclass method. This would result in a nestmate access check if the |
|
34 // super class method is private, which in turn could lead to classloading |
|
35 // and possibly exceptions and cause havoc in the classfile parsing process. |
|
36 // To fix that we added a check for whether the super class method is private, |
|
37 // and if so, we skip the override check as by definition you can't override |
|
38 // a private method. |
|
39 // |
|
40 // This test simply sets up the case where a public subclass method has the |
|
41 // same signature as a private superclass method - the case we now skip when |
|
42 // doing check_final_method_override. The test should trivially complete |
|
43 // normally. |
