Fcr accumulo1.4.x

Yes, that's true, and we discussed this briefly in the GeoMesa chat room, but the feeling was -- as I remember it -- that we needed a replacement for `gt-epsg-hsql` specifically to avoid a conflict with Hadoop.  Matt Williams mentioned that the Hadoop dependency, frustratingly, is only used for some examples (not for mainline code).  This file appears to be the only real replacement for the `gt-epsg-hsql` file.  The text you quote is scary, but  http://docs.geotools.org/stable/userguide/library/referencing/wkt.html gives details supporting this JAR as a reasonable replacement.
