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