Hi Uli,
that was probably missleading. If you don't generate your own precomp-sea data there is no problem at all.
If you DO generate your own precomp-sea make sure that mkgmap uses the trunk version of splitter.jar (or r412).
Don't copy the new splitter.jar into the lib directory of mkgmap.
I think PrecompSeaGenerator will fail early with the wrong splitter.jar.
I've mentioned this because users might simply search for splitter.jar and replace it with the new version from the branch.
Hope this was clearer now?
