| public LinkMessage | receive()Throws IllegalArgumentException if the calling thread is not in the
receiving isolate for this link.
(Note: this differs from the JSR-121 specification, which states that
UnsupportedOperationException should be thrown in this case. That
exception doesn't appear in CLDC, so IllegalArgumentException is thrown
instead.)
