Hi Martin,

I know you are preparing version 1.14 of JTS, and I wonder If you had 
time to review bug reports submitted on sourceforge.

Some notify difficult robustness problem, others are about smaller bugs, 
easier to fix and sometimes including patches.
I went through every bug report in the hope it will help you to sort 
what can be handled before 1.14 release, what
must be postponed and what can be closed.
Note that I did not go through the "patch" section which should also be 
checked before next release.

Thanks for the good work,

7    2009-08-26    gml wrong equals test    solution is given by author 
and easy to implement
8    2009-09-28    topological equality    I could not reproduce the problem
12    2010-12-21    intersection failed    I could not reproduce the problem
13    2011-02-23    non noded intersection    first input geometry seems 
invalid (test builder)
14    2011-05-10    invalid union        first input geometry seems 
invalid (test builder)
15    2011-05-12    RobustDeterminant    I could not reproduced the problem
18    2011-07-04    SpatialIndex insert    I could not figure out what 
the problem is
19    2011-07-10    Simplify empty fails    I could not reproduce the 
problem (test builder)
24    2011-12-12    GeometrySnapper        Snap any point within 
distance instead of the nearest point.
                         I support strk request (maybe difficult to 
include it in 1.14 though)
25    2011-12-14    TopologyException    I could reproduce the problem -
                         Long discussion in 
https://trac.osgeo.org/geos/ticket/488#no1
                                                 Maybe related to #24
29    2012-08-01    Union TopologyException    I could not reproduce the 
problem
31    2012-11-16    Angle.interiorAngle    I agree that results and 
javadoc mismatch
                         not sure what should be changed though
33    2013-02-01    PrecisionReducer    I could reproduce the problem. 
Probbaly difficult to fix before 1.14
34    2013-02-28    NPE            Seems it has already been solved (can 
be closed ?)
37    2013-05-06    IllegalArgumentExc    ...with GeometryCollection. I 
think this is a documented behaviour. Can be closed ?
38    2013-07-04    OraReader        I did not investigate
39    2013-07-30    build broken        Missing OraWriter : repaired ?
                         Other build problems found during tests :
                         jts-jar depends on props
                         jts-test-jar depends on jts-jar
40    2013-10-09    equals and 3D        seems it has been solved on 
H2-GIS side : can be closed ?
41    2013-08-26    intersection        polygon B is not "snapped" on 
polygon A
                         problem inherent to floating point 
approximation : seems difficult to solve without
                         an explicit snapping pre-process
42    2013-09-06    linear referencing    agree that setToEnd seems 
buggy, by chance
                         it seems it is only used by clamp which is only 
used by clampIndex
                         which is not used within the library...
43    2013-10-15    Retina display        I did not investigate
44    2013-11-04    WKBReader        does not handle mixed ByteOrder 
geometries. Probably not too hard to fix
                         but sensible... (I would suggest to postpone to 
1.15)
46    2014-04-21    MultiThreading        some suggestions made by 
author to improve (I did not test)
47    2014-06-12    OraReader/MultiGeom    I did not investigate
48    2014-11-02    Union TopologyException Problem specific to fixed 
precision model. I think in this case, building
                         geometries with fixed precision model lead to 
invalid geometries
49    2014-11-28    ArrayIndexOutOfBounds    with isValid if 
MultiPolygon contains empty polygons
                         suggestion made in the ticket to fix the problem
50    2014-11-28    Geometry.compareTo    inconsistent (compare only 
exterior ring)
                         suggestion in the ticket to fix the problem
51    2015-01-28    Infinite loop        in preparedPolygon. Problem 
still there : patch submitted by ticket author
52    2015-05-01    Licence            outdated address : report 
includes the new address
53    2015-09-16    RayCrossingCounter NPE    Not tested, report 
includes easy suggestion to fix the problem
