Unexpected output from OffsetCurve.getCurve() since jts-version 1.20.0

Start with the Java example calling OffsetCurve.getCurve() and reproduce the differing output under JTS 1.19.0 and 1.20.0. Inspect the “Improve Buffer ring simplification” commit mentioned in the issue, then determine whether the changed gaps are expected or whether parameters or implementation need adjustment; the issue is done when the behavior and a compatible path are documented or corrected.

Hi!
I recently updated my jts-version from 1.19.0 to 1.20.0 and stumbled across some unexpected output from the OffsetCurve.getCurve() method.
I use this method to create lines with a constant distance, but after updating to 1.20.0, the output changed.
This code was used to create the images below:

    GeometryFactory geometryFactory1 = new GeometryFactory();

    LineString testLineString = geometryFactory1.createLineString(new Coordinate[]{
            new Coordinate(-477.9727884893793, 726.8346522633758),
            new Coordinate(-278.5761790410716, 469.3177193695431),
            new Coordinate(-79.17956959276393, 211.80078647571045),
            new Coordinate(-74.10825983114643, 205.2512862651522),
            new Coordinate(-61.59032155710979, 183.66416102497575),
            new Coordinate(-56.17516937041343, 177.39645645603244),
            new Coordinate(-45.87664216572637, 163.28009296700202),
            new Coordinate(-32.80606824944878, 140.06145723770865),
            new Coordinate(-26.625732783814613, 132.27313760006422),
            new Coordinate(-20.81619693653508, 123.16499838643774),
            new Coordinate(-15.495636510039938, 116.78652899133516),
            new Coordinate(-9.117773193378609, 108.03384392886659),
            new Coordinate(9.065051143785869, 79.15745454413279),
            new Coordinate(25.818482523651234, 55.05549100891343),
            new Coordinate(211.71012482617877, -212.37351996146882),
            new Coordinate(397.60176712870623, -479.8025309318511)});

    for (int i = 1; i < 100; i++) {
        LineString offsetCurve = (LineString) (OffsetCurve.getCurve(testLineString,
                -i * 0.775).getGeometryN(0));
    }

Using this code with jts-version 1.19.0, I got this image (zoomed in into the "interesting" part):

With 1.20.0, I got this:

I hope, you can see the gaps between some of the offset curves.
Since I need the output of version 1.19.0, I wanted to ask if this is some kind of bug or if the behaviour of getCurve() changed.
Is there a way to get the output of 1.19.0 by calling the method with different parameters?

(Additional note: I checked the output of the code above for older versions and the behaviour changed with the commit "Improve Buffer ring simplfication" (22.11.2023).)

Thanks in advance!
