Result of DescribeProcess request for process _de.hsbo.wacodis.land_coverclassification cannot be parsed with 52North wps-client-lib

This issue does not appear with the other algorithms, e.g. de.hsbo.wacodis.snap.s2togeotiff or org.n52.javaps.service.TestAlgorithm. The issue could also be caused by 52North wps-client-lib.

Easiest way to reproduce:

  1. run wps web app with wacodis backend locally
  2. edit variables wpsURL and processID in class org.n52.geoprocessing.wps.client.WPSClientExample.java of 52North wps-client-lib
  3. run org.n52.geoprocessing.wps.client.WPSClientExample.java (exception is already raised when retrieving process description).

The cause for the described issue is not located in this repository. Since the used wps-client-lib contains unimplemented support for ows:AllowedValues, the issue is regarding to https://github.com/52North/wps-client-lib/. The issue has been solved by WaCoDiS/wps-client-lib@f39057e and thus can be closed.
