[mkgmap-dev] mkgmap/generate-sea=extend-sea-sectors problems

Hi,

I'm building my own OSM map for Garmins since quite some time,
but now I wanted to fix the issue, that the sea isn't drawn
correctly. For this I played with the generate-sea option.
But independent to which value I set this option, I always
get this java error after quite some time:

java.lang.ClassCastException: java.util.TreeMap$1 incompatible with java.util.NavigableSet

Exiting - if you want to carry on regardless, use the --keep-going option

I tested snapshot 1812 and 1829.

Any idea what causes this and how to fix/workaround this?

 Thanks,
