"Clean up and return" after JNU_ThrowOutOfMemoryError

This bug breaks out the awt portions reported in bug 6188718. All fields from that bug have been duplicated here where applicable.

Native JVM support routines make calls to JNU_ThrowOutOfMemoryError,
e.g. when a malloc has failed.

They must not then go on to assume the Throw... does not return.
e.g. do not use the value that came back from the failed malloc.
