* @summary Test nestmate checks are no longer used when check_final_method_override is executed during parsing
* @run main TestFinalMethodOverride
*/
// 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.
public class TestFinalMethodOverride {
public static class Super {
private final void theMethod() {}
}
public static class Inner extends Super {
// define our own theMethod
public void theMethod() {}
}
public static void main(String[] args) {
Inner i = new Inner();
}
}
