it seems that getNodeTypes() and getNodeNames() in NodeTypes where never used until now :-)
from jbpm-jpdl-3.2.1 getNodeTypes() is returning nodeNames and vice versa.
package org.jbpm.graph.node;
public class NodeTypes {
public static Set getNodeTypes() {
return nodeNames.keySet();
}
public static Set getNodeNames() {
return nodeTypes.keySet();
}
