Re: [Jts-topo-suite-user] Java 7 Issues

[Martin D. <mtn...@gm...>]

I'm still not seeing the error, even using those buffer distances.  Can you
post your Java version info?

Myu test environment is:

java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)
