[rules-users] compiled processes in PKG removed by knowledge agent after first change scan

hi, I'm having trouble with scanning changed knowledge from Guvnor. I found out that compiled processes from Guvnor are missing after resource change scanner scan for changes first time (event there is no changes). I wrote a simple test to reproduce this. public class KnowledgeAgentTest { @Test public void should_load_processes() throws Exception { ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); // Scan change every 2 seconds KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("agent"); // Changeset points to a PKG contains 12 processes on Guvnor kagent.applyChangeSet(ResourceFactory.newClassPathResource("test/drools-changeset.xml")); // Everything is still ok now System.out.println("Processes before scan: " + kagent.getKnowledgeBase().getProcesses().size()); Assert.assertFalse(kagent.getKnowledgeBase().getProcesses().isEmpty()); // Scan change every 2 seconds sconf.setProperty("drools.resource.scanner.interval", "2"); ResourceFactory.getResourceChangeScannerService().configure(sconf); ResourceFactory.getResourceChangeScannerService().start(); ResourceFactory.getResourceChangeNotifierService().start(); // Wait long enough Thread.sleep(5000); // Processes are gone somehow System.out.println("Processes after scan: " + kagent.getKnowledgeBase().getProcesses().size()); Assert.assertFalse(kagent.getKnowledgeBase().getProcesses().isEmpty()); } } Here is what I'm getting when run the test. ------------------------------------------------------- T E S T S ------------------------------------------------------- Running test.KnowledgeAgentTest Processes before scan: 12 Processes after scan: 0 Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 5.802 sec <<< FAILURE!
