[JTS works] TopologyException in ST_Union with valid geometries

Description

In 3.3.6 a lot of issues with my dataset have been resolved but another one popped up shortly after today's release.

Attached is an SQL script with a number of geometries that are all valid. At the end of the script there's ST_Union aggregate which throws: 

ERROR:  GEOSUnaryUnion: TopologyException: found non-noded intersection between LINESTRING (7.85872 48.7632, 7.85864 48.7631) and LINESTRING (7.85864 48.7631, 7.85864 48.7631) at 7.8586359309477531 48.763120943813725

Resolution: → fixed
Status: new → closed

I cannot reproduce here with POSTGIS="2.1.1dev r12013" GEOS="3.4.3dev-CAPI-1.8.3 r3958" Assuming fixed by 3.3.something (tried 3.3.9?) -- reopen if you cannot confirm
