Hi WanMil,
I have coded a small test that tries to detect these "spike-like" areas. Idea: If the area size is much smaller (I used 20 as a threshold) than that of the bounding box we should remove the way from the area.
This patch does at least not fix my problem, still get exact the same stack trace. Thorsten
I am not sure regarding the threshold value, but I think the principle is ok. What do you think?

Hi Thorsten,
I can confirm this problem. I can repdroduce it with a "boundary" which contains these 4 points: [2412980/371559, 2412981/371558, 2412992/371544, 2412980/371559] The Way.clockwise() method says it is counter-clockwise. Besides rounding errors, it is a line, not a shape, and I guess that causes the problem. The clockwise() method calculates an area size of 3, which is almost zero.
It is quite likely that the intersection of two areas produces these "nearly empty" (parts of) areas, what we need is a filter that throws them away.
I am not sure if WanMil is already working on this?
