if this failure can be reproduced consistently, you could add the following properties to the run command of the test
-Dsun.rmi.runtime.logLevel=VERBOSE -Djava.rmi.server.logCalls=true -Dsun.rmi.server.logLevel=VERBOSE -Dsun.rmi.transport.logLevel=VERBOSE -Dsun.rmi.transport.tcp.logLevel=VERBOSE -Dsun.rmi.dgc.logLevel=VERBOSE
i.e.
@run testng/othervm -Dsun.rmi.runtime.logLevel=VERBOSE -Djava.rmi.server.logCalls=true -Dsun.rmi.server.logLevel=VERBOSE -Dsun.rmi.transport.logLevel=VERBOSE -Dsun.rmi.transport.tcp.logLevel=VERBOSE -Dsun.rmi.dgc.logLevel=VERBOSE FilterUROTes

these will produce log traces on stderr, which is recorded in the test's jtr file, and in the event of the failure occuring this trace might be useful in the diagnosis of the issue, for example, whether or not the removeTarget method is being invoked on the ObjectTable. You will see objects being added with trace such as:

FINER: MainThread: add object [0:0:0, 2]

FINER: MainThread: add object [-3d215748:18634027149:-7fff, 248225399703400139]
