Thanks for joining us on the user list Juan. I expect we will need to
report this to the issue tracker.
Quickly looking at the source code of that class we can see one reference
to LINEARIZATION_TOLERANCE:
Double linearizationTolerance = (Double)
hints.get(Hints.LINEARIZATION_TOLERANCE);
if (linearizationTolerance != null) {
geometryFactory = new CurvedGeometryFactory(geometryFactory,
linearizationTolerance);
}
So this looks to be at the java code, and not part of your MySQL setup. I
am confused about why this would be different between windows and linux
however?
