You should be able to use a DouglasPeuckerSimplifier to achieve this.
Something like:
DouglasPeuckerSimplifier simplifier = new DouglasPeuckerSimplifier(in);
simplifier.setDistanceTolerance(tolerance);
Geometry out = simplifier.getResultGeometry();
would do it.
JTS also provides a TopologyPresersevingSimplifier and a
LineSegmentSimplifier that would also handle your case.
