[Jaroslav Bachorik]

JMX related tests have hard time running in "agentvm" mode because they
need a set of privileges which are not granted by the default security
manager. For this reason all the tests from javax/management are forced
to run in "othervm" mode.

com/sun/jmx/remote/NotificationMarshalVersions/TestSerializationMismatch.java
must also be forced to run in "othervm" mode.
