Towards Jena 6.2.0

Apache Jena 6.1.0 was released on 2026-05-03 so it's time to think about 
releasing 6.2.0.

-----------------------------

== Of note:

Working Group - RDF and SPARQL:

Syntax (Turtle etc, SPARQL etc) are UTF-8 documents. UTF-8 does not 
allow surrogate pairs.  The RDF Working Group has decided not to allow 
surrogate pairs via Unicode escapes.

In GeoSPARQL:
* upgrade SIS upgrade 1.4 -> 1.6
* support non-Euclidean geometries

In Fuseki:
* Memory leak fix related to long-running servers using Apache Shiro

In TDB:
* Robustness fix for the database after system level error
   This affects both TDB2 and TDB1.

At this point, there will need to be a quiet time to sort out a release. 
If not, the release will keep slipping later and later.

So from now, only small, low risk changes; the rest will have to wait.
