Research direction
Start by tracing the failure through Proj4Parser.java and CRSFactory.java, then inspect how existing projections are registered and tested. Add support for the rHEALPix projection so the shown createFromParameters call no longer reports an unknown projection, and verify it with an appropriate existing projection test pattern.
