[rmi] supressStackTraces does not suppress suppressed exception

[ecki at zusammenkunft.net]

Hello

I noticed that RMI servers honor the sun.rmi.server.suppressStackTraces system property only for the
`cause` member, but not for the suppressed exception array. This seems to be not documented (and is most
likely not wanted?)

It looks like it does also not handle SQLWarning#getNextWarning() chains, but I guess this is not expected.

With suppressed remote stacks:
