Actually it's not quite that simple. I think there have been some
other slight changes to the transaction handling. But if you look at
the differences between 0.9 transactions and 1.2 you should be able to
update jcifs-ext. But ...

RAPs are limited to 64K payloads. Only 8 groups sounds pretty small. Maybe
some buffer sizes need to be fiddled with. But you're still going to hit
the limit. The correct method is to use RPCs. Some people have managed
to get one or another RPCs working with Jarapac. Actually I think using
Jarapac would probably be the easier way to go. Search the list.
