I don't remember particular changes in the referencing subsystem
between 2.1.x and 2.2.x, you may also try your luck
with the older EPSG database on the 2.2.x series and see what the
reprojection console says about the transformation

Squirrel SQL is my client of choice (generic JDBC client, you have to configure
the JDBC url and point it to the EPSG database while GeoServer is powered off)
