pageflow parsing is slow
------------------------

                 Key: JBPM-1707
                 URL: https://jira.jboss.org/jira/browse/JBPM-1707
             Project: JBoss jBPM
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Core Engine
    Affects Versions: jBPM 3.2.3
         Environment: Red Hat Enterprise Linux AS release 4 (Nahant Update 7)
enterprise-installer-4.3.0.GA-1.ep1.8.jar
jdk-1.5.0_16-fcs
            Reporter: Alejandro Guizar
            Assignee: Alejandro Guizar
             Fix For: jBPM 3.3.0 CR1


On a RHEL machine, while deploying a seam based ear, which contains 13 pageflow definitions, the parsing of these 13 pageflow files takes more than 34 minutes (!).

The culprit seems to be the usage of the original systemId (http://jboss.com/products/seam/pageflow-2.0.xsd) in the org.jbpm.jdpl.xml.JpdlParser$JpdlEntityResolver class, as this 
apparently results in slow internet lookups:

   log.debug("original systemId as input source");
   inputSource = new InputSource(systemId);

Using a null InputSource:

   inputSource = new InputSource((InputStream)null);

brings the parsing time down to less than 1 second.

Of course it would be better to actually pass in a reference to the local pageflow-2.0.xsd file, which is inside the jboss-seam.jar.
