How to get deserialized JTS Geometry field in Grails 4?

问题

I'm building a small Geo server using PostgreSQL + PostGIS + Grails 4 + Geoserver + React + JTS. The domain class has a com.vividsolutions.jts.geom.Point field that is maped to a sqlType: 'geometry(Point,4326)'. When I search any findBy...(...) search, I cannot get the result, as it is not posible deserialize

in Grails 2.x I did not get this problem. It's my first time programming in Grails in 3 years.

package ....

import com.vividsolutions.jts.geom.Point

class Aqop {
  String  pid
  String  pname
  Float   x
  Float   y
  String  srid
  Point   center

  static mapping = {
    table         'aqop'
    version       false
    autoTimestamp false
    cache         true

    id     column: 'aqop_id'
    pname  column: 'pname',  type: 'text', index: 'aqop_pname_idx'
    pid    column: 'pid',    type: 'text', index: 'aqop_pid_idx'
    x      column: 'x'
    y      column: 'y'
    srid   column: 'srid',   type: 'text'
    center column: 'center', sqlType: 'geometry(Point,4326)'
  }

  static constraints = {
    pname size: 1..128, unique: true
    pid   size: 1..64,  unique: true
    x     nullable: false
    y     nullable: false
    srid  nullable: false, size: 1..64
  }
}

This the error message:

How camn I get deserialized the Domain Object ? Any help is welcome and thanks in advance.

According to documentation Grails 4 is compatible with latest version of Hibernate 5.4.
Karel Maesen in linked issue comments that latest versions of Hibernate expect latest versions of JTS.
Migrate your dependency from vividsolutions.jts to locationtech.jts and define Point as org.locationtech.jts.geom.Point More info: https://github.com/locationtech/jts
