     * IMPORTANT: sometimes the build of the BPMN2 might fail for minor reasons, including things like
     * a bad script in a script task
     *
     * When this happens, we (re)parse the process definition, but do not completely "build" it
     * (as in, what org.jbpm.compiler.ProcessBuilderImpl.buildProcess(Process, Resource) does).
     *
     * It *would* be more efficient to basically copy/paste the
     * jbpm-flow-builder org.jbpm.compiler.ProcessBuilderImpl.addProcessFromXml(Resource) logic here,
     * so that we do something like:
     *
     * 1. Use the XmlProcessReader to create a process
     * 2. *try* to build the rest of the process (and fail safely if not)
     * 3. do XmlProcessReader.getProcessBuildData().onBuildComplete(process)
     *    to complete collecting the information
     *
     * But... that's a high maintenance cost for this piece of software
     *
     * So until we can refactor the ProcessBuilderImpl logic (using functional logic for conditional handling?)
     * to be used here, let's keep it simple (as in, parsing the BPMN2 a second time when the build fails..)
