Upgrade to Lucene 6.4.1 in jena-text and jena-spatial (JENA-1250)
These two commits will upgrade jena-text and jena-spatial to use Lucene
6.4.1 (and spatial4j 0.6).
Things to note:
* The Lucene index format is incompatible. Old indexes need to be
recreated. There is no backward compatibility, since we are going two major
versions up and Lucene generally supports only the index format of the previous
major version.
* The multilingual analyzer has been reimplemented to use a different field
layout where every language gets a separate field (e.g. label_en, label_fr) as
well as a single generic field (label). This had to be done due to API changes
in Lucene 5 that made it impossible to use the old mechanism where a single
field was used for all languages.
