IIRC, the situation back then was a bit different. The JPA JAR could simply
be made usable with Java 6 as a matter of build configuration, while now a
dependency explicitly requires Java 7.

Sure, we could still support running on Java 6 when not using queries (or
when not using the HSEARCH based parser backend), but given that this is
the default parser backend for all dialects except for MongoDB I doubt that
this is of much use. Also it has been a year since then in which more
projects have been migrating off 6.

Anyways, we had the discussion before and agreed to stick on 6 for OGM for
the time being. When going to HSEARCH 5, we'll require 7 instead in many
cases. That's the effect I wanted to point out to make sure we're all aware
of it. Personally I'd go for 7 altogether, but I'm fine with it either way.
