After many attempts (did I mention I hate java and ants with a passion ?)
I finally succeeded in having JTS run its unit tests and _surprise_ (?)
it fails as well:

(1)
    [junit] Testcase: testDaveSkeaCase(test.jts.junit.algorithm.RobustLineIntersectionTest):    FAILED
    [junit] Number of intersections not as expected expected:<2> but was:<1>

(2)
    [junit] Testcase: testCmp5CaseWKT(test.jts.junit.algorithm.RobustLineIntersectionTest):     FAILED
    [junit] Int Pts not equal - POINT ( 4348437.0557510145 5552597.375203926 ) vs POINT ( 4348440.8493874 5552599.27202212 )

(3)
    [junit] Testcase: testCmp5CaseRaw(test.jts.junit.algorithm.RobustLineIntersectionTest):     FAILED
    [junit] Int Pts not equal - POINT ( 4348437.0557510145 5552597.375203926 ) vs POINT ( 4348440.8493874 5552599.27202212 )


If you're curious about how I handled to run the JTS unit tests:
