Comments
SQE is ok to take the fix in PSU15_04.

Adding critical watch since the jdk7/6 backports are related to JDK-8076110, and should be fixed at the same time if possible.

I disagree that this issue appears only on artificial testcases. I hit it while trying to gather code coverage using jcov in dynamic instrumentation mode. Code coverage tools shouldn't care about such limitations on VM implementation. Hotspot can support or ignore redefinition of finalize(), but it should not issue any error. Otherwise, it's a specification violation.

This issues appears on artificial testcase only.

Artificial testcase redefine empty Object::finalize() to non-empty one. Despite the fact that spec doesn't limit methods that can be redefined, hotspot doesn't support this kind of redefinition.

EVALUATION in ClassFileParser::set_precomputed_flags() we check nearest super only when setting has_finalizer flag, but under assert we check all supers up to the java.lang.Object. So if we inject finalizer somewhere in the hierarchy it cause the difference between results of these two computations and assert will fail.
21-03-2012
EVALUATION I think the problem is that a klass is being changed from not having a finalizer to having one and that's really not going to work. Existing objects haven't been registered for finalization so their finalizer will never be called. I suspect this case should be rejected. Any change in finalizable should be rejected.
