RuntimeException: Less than three points

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Trying to compile a map with this data http://download.geofabrik.de/osm/
europe/germany/schleswig-holstein.osm.bz2

What is the expected output? What do you see instead?
I get an error message:
Exception in thread "main" java.lang.RuntimeException: Less than three

What version of the product are you using? On what operating system?
Using svn-readonly-checkout from 27-11-2009 - 15:53
OSM-Dataset off the same day

Please provide any additional information below.
Exception should be caught in a more user-friendly way. For example by 
message-output and removing the polygon from the dataset.

I'll try to solve this myself and send a patch

I had similar problem with my dataset. I think it's reasonable to just to skip 
the offending elements. Patch is here:
