The failures below are seen when interoperating between rmi-iiop and idl-java
clients and servers.
Also, elements get missed from passed wchar arrays.

The rmi-iiop implementation (in ValueHandler) is incorrectly
marshalling/unmarshalling arrays of Java char as single octet chars.

Fixing this problem renders the ORB incompatible with previous versions.

Testcases are available, but consist of 30+ files.  Contact me for a zip file if required.

======================================================================

N/A

We should be able to extend our versioning work to encompass this change so as not to break backwards compatibility with our legacy ORBs.

We will fix this in Ladybird as part of bug 4365188.
