That would be org.hibernate.spatial.dialect.postgis.PGGeometryTypeDescriptor. The method <tt>toGeometry</tt> tries to parse the PGobject either as WKT or WKB. But the check is flawed, as it expects every WKT to begin with an SRID and therfore is only valid for EWKT. A geometry without SRID will throw a NumberFormatException as it tries to parse a WKB:</p>
