RFR: 8268094: Some vmTestbase/nsk tests fail after ACC_STRICT/strictfp changes

[David Holmes]

Part of the JEP-306 integration wasn't tested past tier 3 and missed some changes needed in the vmTestbase/nsk tests. The crux of the changes for JEP-306 are that the strictfp modifier has no affect any more (all fp math is strict) and is not observable as a modifier. At the VM level ACC_STRICT is no longer defined for classfiles version 61+ (ie JDK 17+).

Affected tests:

- vmTestbase/nsk/jvmti/GetMethodModifiers/methmod001/

This test has a part that expects to read the ACC_STRICT modifier for a strictfp method - so that part is just deleted.

Other jvmti test files refer to ACC_STRICT (but don't test anything) and so those references are also deleted.

- vmTestbase/nsk/jdi/VirtualMachine/redefineClasses/redefineclasses007.java
- vmTestbase/nsk/jdi/VirtualMachine/redefineClasses/redefineclasses008.java

These each have two subtests (07 and 08) that test changing the strictfp modifier on a method. These subtests are just deleted.

Testing:
 - local testing of affected test areas
 - tiers 1-5 also submitted for good measure (but may take a while to run and should not delay getting these fixes in places so that the CI returns to normal - thanks).

Thanks,
David
