[infinispan-dev] Dropping support for older versions of Apache Lucene

[Sanne Grinovero]

All,
please note I've sent the pull request which removes support for
Apache Lucene versions 2.x and 3.x [1]

The currently recommended version is Apache Lucene 4.8.1; if someone
has really strong needs to keep support for Lucene 3 please speak up
now as the patch is rather large and complex.

However the primary reason for us to drop this, is that it makes it
very tricky and time consuming to develop a better integration with
Lucene 4+ so I don't think it will be possible to maintain the support
for the older version, unless someone volunteers for it.

Note that the Query engine and all such extras we built on it, were
already migrated to Lucene 4 so there is no loss of other
functionality.

Regards,
Sanne
