[mkgmap-dev] mkgmap r2179: Still NullPointerException in BoundaryUtil

Tue Jan 24 21:30:50 GMT 2012

Hi,

in case your are right Gerd (I have no time today to check that in 
deep), it is a bug of the clockwise method. So this method needs a 
bugfix - not the parts that use the method clockwise method.
