Good idea! I set it on my watch list.

??? My rt.jar is 46 MB. Can you explain your numbers?

In IBM933.map you state:
# (2) we "should" have an entry
# 25 000a
# in IBM933.nr (b->c only tables) as other ebcdic
# mappings do, but the "old" implementation actually
# maps \u000a to 25. Keep it old behavior for now.
I think we shouldn't stick on old behaviour here, as there obviously was
an error in old code, but nobody filed a bug until now.

I would be happy to see my name in 2nd/3rd position. :-)
