[Info-vax] Java portability and VMS

[Wendell]

I have been looking for info regarding Java on OpenVMS and
portability. The only thing I found so far is here:
http://h71000.www7.hp.com/openvms/journal/v10/javavms.pdf

Some quotes:

"...Java programs are much more portable than those written in a
compiled language. However, we are still a long way from verifying
total portability...The Java library creators, VM developers, and
application developers are mainly from the UNIX world and, therefore,
are unfamiliar with OpenVMS..."

"...the majority of Java applications use file names that do not
respect ODS-2 file semantics. If this is the case then it is vital
that the file system be migrated to ODS-5 format..."

"...Java ignores the notion of file versions..."

"...The problems the Java developer encounters most often concern
process management (such as fork, environment variables) and can be
only resolved by modifying the source code and recompiling the
application..."

Of course, it always takes special care to write Java programs to be
platform-independent, but this sounds like any significant application
would require special porting to run on VMS. Is that true?
