/**

*
* Verify the GIOPConnection::receiveMessagesLoop handles OutOfMemory. This
* test uses ByteMan to inject an OutOfMemory condition in the code where
* it was reported:
* <pre>
* Exception in thread "ClientMessageReceptor0" java.lang.OutOfMemoryError: Java heap space
* at java.util.Arrays.copyOf(Arrays.java:2271)
* at java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:113)
* at java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:93)
* at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:140)
* at org.jacorb.orb.giop.GIOPConnection.receiveMessagesLoop(GIOPConnection.java:641)
*</pre>
* This then allows verification that the code can handle the fault condition and the client
* receives an exception and doesn't hang.
