Hi all,
Recently, I encountered an odd problem when I run my program using
GeoTools (v8.0-M4) on 64-bit Java environment, the output of the same
program with the same input will different on different computer and even
different running. Then I carefully debug my program and finally found the *
org.geotools.geometry.jts.JTS.transform* method on some 64-bit environment
will produce a little different result from the one on 32-bit environment.
The problem may be related to the computation accuracy. I found the problem
not happened on 64-bit Windows 7 and 64-bit Ubuntu, but happened on the
64-bit RedHat Enterprise.
I don't know the cause of the problem, and whether GeoTools could
running correctly on 64-bit environment. So I hope the developers would
give me some tips about that, and I suggest you to consider to design and
test GeoTools for 64-bit more.
Thanks very much!
