In the end it took about 5-6 hours for the java file generation to
finish 
and then it bombed out for lack of memory when it spawned a javac job to
compile the java sources.

The problem can be avoided by not using the COMPAQ True64 supplied JVM 
(both 1.3.0 and 1.2.2). On an intel linux box running the HotSpot 1.3.0
JVM it completed in 10 minutes and consumed about 50Megs of RAM.

Doubtless no one else will ever encounter this problem. 
This message was just for completeness.
