> 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). 
> It looks similar to JBRULES-2293, but I'm loading knowledge from Guvnor
> I wrote a simple test to reproduce this. (tried with Drools 5.2.0.Final and Drools 5.3.0.CR1) 
> 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.
