      Description

      WPS execute request ends in:

      org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException:
      index=0, size=0
      at org.eclipse.emf.common.util.BasicEList.get(BasicEList.java:512)
      at org.geotools.data.wps.WPSUtils.createResultMap(WPSUtils.java:380)
      at org.geotools.data.wps.WPSProcess.execute(WPSProcess.java:143)

      I guess (no proof) this result parameter containing a base64 encoded and zipped shapefile could be the reason:
      <Output>

      <ows:Identifier>IdentifiedAffectedAreasFeatureCollection</ows:Identifier>
      <ows:Title>The resulting feature collection that contains the
      Identified Affected Areas (returned as a zipped shapefile)</ows:Title>
      <ComplexOutput>
      <Default>
      <Format>
      <MimeType>application/zip</MimeType>

      <Encoding>base64</Encoding>
      </Format>
      </Default>
      <Supported>
      <Format>
      <MimeType>application/zip</MimeType>
      <Encoding>base64</Encoding>

      </Format>
      </Supported>
      </ComplexOutput>
      </Output>

      A solution could be not to inline the result but to advice the WPS to return only the URL for the result/resource. Currently setting 'asReference="true"' for response parameters is not possible.

      <wps:Execute>
      ...
      <wps:DataInputs>
      ... input parameters here
      </wps:DataInputs>
      <wps:ResponseForm>
      <wps:ResponseDocument>
      <wps:Output asReference="true">
      <ows:Identifier>IdentifiedAffectedAreasFeatureCollection</ows:Identifier>
      </wps:Output>
      <wps:Output>
      <ows:Identifier>NumberOfIdentifiedAffectedAreas</ows:Identifier>
      </wps:Output>
      <wps:Output>
      <ows:Identifier>TotalProcessExecutionTime</ows:Identifier>
      </wps:Output>
      </wps:ResponseDocument>
      </wps:ResponseForm>
      </wps:Execute>
