Benchmark doesn't allow for de-serializing XMLs with references
---------------------------------------------------------------

                 Key: JBRULES-3208

             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-planner
    Affects Versions: 5.3.0.Beta1, 5.2.0.Final
         Environment: java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.3) (fedora-59.1.10.3.fc15-x86_64)

            Priority: Critical


I have a solution configuration serialized via XStream [1]. When I'm attempting to benchmark [2] my solver with that solution, I get the following error:

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2:java (default-cli) on project tournaments: An exception occured while executing the Java class. null: InvocationTargetException: Problem reading unsolvedSolutionFile: src/main/resources/input-tiny.xml: Invalid reference
[ERROR] ---- Debugging information ----

[ERROR] version             : null
[ERROR] -------------------------------

I can see two solutions:
a) Make it so that Planner benchmark does understand XStream's XML.
b) Provide a method inside Planner to serialize Solutions in a way that benchmark will understand them later.
