This is a mirror bug for
  4697804   nsk/regression/b4432433 fails with java.lang.OutOfMemory Exception

A common case for bailing out to vm_exit_out_of_memory due to low
resource conditions was fixed in 4697804 for the default collector only.

Other collectors which hook up with DefNewGeneration (more generally,
which hook up with a young generation collector which doesn't implement
promotion undo) will still hit that case until they implement
  Generation::commit_contiguous_available(size_t bytes)

Currently, only OneContigCardSpaceGeneration implements this method.

N/A

This is just one case where we avoid vm_exit_out_of_memory.  
Also, the default implementation is optimisitic in that 
Generation::commit_contiguous_available returns true to 
preserve the current behavior, but maybe that should change 
when the rest of the Generation subtypes actually implement 
this method.

We decided not to check in Generation::commit_contigous_available, as
we'd prefer to catch out-of-swap situations early and fail. The alternative
is to allow the VM to continue, but potentially fail in other ways due to
low-swap (often, libthread will fail as VM exit involves running the
exit hooks, so threads are started).

Therefore, this bug is against non-existant code and is being closed.
