I'm observing an OutOfMemoryError when accessing the ORBacus IFR with a corbaloc:iiop:localhost:1070/DefaultRepository. See stack trace below. The value of len in IdEncapsulationBase.readOctets is 778530159 (>700MB).

We should catch unmarshaling errors like this one returning a MARSHAL instead of giving up with OutOfMemoryError. There are possibly more places like this in the stream unmarshaling code.
