Here's an updated webrev that includes the change to bind to the stub.
The jstatd tests continue to pass after this change.

It would be good to have a second reviewer from the serviceability team.
Longer term it would be good to replace the rmi dependency, which does not
appear to be central to the functionality provided here.

Hi Gary,
Holding a static reference to the implementation solves the problem.
But I noticed that the object that is bound in the registry is the
RemoteHostImpl
and it should be the RemoteHost stub.
Line 145: should be:
bind(name.toString(), stub);
That is likely to solve the problem as well, because the distributed
garbage
collector will correctly cause a hard reference to be retained to the
implementation.

Here's a proposed fix for the intermittent jstatd test failure.
By moving the exported object from a local method variable to a
static class variable a strong reference is held so the object
will not be garbage collected prematurely.

The test is currently filed as a core-libs/java.rmi, but it probably
should be core-svc/tools with label=jstatd. It is the callers
responsibility to ensure the strong reference to prevent
the premature garbage collection, so this is a test failure
rather than a need to change the underlying rmi behavior.
