The HotSpot VM does not implement sun.tools.debug (STD).
An attempt to use it generates an "InternalError" (see below).
Either 1) Code must be removed; or 2) Must be visibly documented.

These tests are still failing in Ladybird build 18 and Merlin build 54. As I understand it, the debug code has been removed from the Solaris products. If this is the case, these tests should be modified so they don't run on Solaris. To exit rc, there has to be zero regression failures in Ladybird.

Of course they are still failing! They will never ever work again.
Sun.tools.debug only works under the Classic VM. There is no Classic VM
on Solaris in 1.3 and Ladybird. As of Merlin, Classic VM will not be
part of any system we ship and thus sun.tools.debug will never run again.
There is exactly one solution - for Ladybird, do not run sun.tools.debug
tests on Solaris, for Merlin you MUST remove all sun.tools.debug tests.
