Thanks, Arne.

I don't use any of the gotchas you mention - nothing, really, outside the 
what was in the 1.6 standard library, apart from some 3rd party stuff:

- the Coco/R syntax generator 
- RiverLayout, 
- a geodesy package,
- dnsjava,
- mail stuff (jaf ?, javamail, mstor)
- jcharset
- jdbc for PostgreSQL

so it looks as though the move should be straight forward.
