Try tis polygon with JS version:

-816 657,
-822 644,
-822 945,
-816 952,
-810 957,
-810 669

after adding some (small) jitter, I can get it to work, 50% of time.

The JS version is a community port of poly2tri so I can't really help you with 
why it doesn't work :/.

The epsilon values in poly2tri was picked to get best precision when points are 
in the range -1,1. Maybe try to rescale and see if you can get better 
precision, but I doubt this is the issue in this case.

I tried given pointset with the Java version and it works fine.

This is duplicate of #44 , it even includes a patch, can you update your repo 
or do you really insist on a silly path file?

I have applied that patch. Would like to understand why it is needed since it 
isn't needed in the java version. 

Oh well. If it works it works :P
