To date then the directories containing the CORBA and RMI-IIOP tests 
have been in the jdk_other group. I think it would be best not to have 
them split between two groups. Adding this to jdk_other should do it:

javax/rmi \
-javax/rmi/ssl

You might need to look at the exclusiveAccess.dirs property in TEST.ROOT 
to avoid several tests trying to run orbd at the same time.

Stuart has been battling a bunch of issues in other areas with "address 
already in use" and may have some advice on how to approach this test. I 
do see that orbd can run on other ports and also it might be possible to 
start it via it's com.sun API rather than the launcher.

This may be something to add to the testlibrary infrastructure.
