RFR: 8252593: [TESTBUG] serviceability/jvmti/GetLocalVariable/GetLocalWithoutSuspendTest.java failed with JVMTI_ERROR_INVALID_SLOT

[Richard Reingruber]

Continuing review [1] after transition to Git/Github.

I still cannot reproduce the issue.

RFC on alternatives:

1. Integrate this change and ignore future JVMTI_ERROR_INVALID_SLOT
2. Don't ignore JVMTI_ERROR_INVALID_SLOT but integrate the rest of this patch. If the test still fails with
JVMTI_ERROR_INVALID_SLOT we will at least know the depth of the frame. 3. Add trace code to VM_GetOrSetLocal in
!PRODUCT or ASSERT configurations depending on an option or property.

Any other ideas?

I'm in favour of 1.
