I am well into the Java port, but have not done any work in the last 
couple of months owing to a house move. My first priority is the 
renderer - the S57 conversion will come later (NB: s57toosm was a 
subsidiary project of searender to leverage use of the look-up tables).

I recommend that only the "nodes" option is used in s57toosm as the 
line/area processing is incomplete & can generate invalid OSM files (or 
crash). I have since delved deeper into the encoding of S57 vector 
objects & have addressed these issues in the Java code. This new work 
cannot easily be ported back to s57toosm as I have completely changed 
the architecture and internal map model structure in the new program.
