Injection of KernelController fails in bootstrap xml ---------------------------------------------------- Key: JBMICROCONT-176 URL: http://jira.jboss.com/jira/browse/JBMICROCONT-176 Project: JBoss MicroContainer Issue Type: Bug Affects Versions: JBossMC_2_0_0 Beta3 Reporter: Scott M Stark Assigned To: Ales Justin If I attempt to the KernelController into the HDScanner defined in the conf/bootstrap-beans.xml using: <!-- Hotdeployment of applications --> <bean name="HDScanner" class="org.jboss.system.server.profileservice.hotdeploy.HDScanner"> <property name="mainDeployer"><inject

org.jboss.Main$1.run(Main.java:522) at java.lang.Thread.run(Thread.java:595) Going through the code, the failure occurs because the AbstractDependencyValueMetaData.getValue requires a property != null && lookup instanceof AttributeDispatchContext. The lookup in this case is a KernelRegistryEntry, so the property value is not retrieved and instead the bean is used as the value. public Object getValue(TypeInfo info, ClassLoader cl) throws Throwable { ControllerState state = dependentState; if (state == null) state = ControllerState.INSTALLED; Controller controller = context.getController(); ControllerContext lookup = controller.getContext(value, state); if (lookup == null) throw new Error("Should not be here - dependency failed! " + this); Object result = lookup.getTarget(); if (property != null && lookup instanceof AttributeDispatchContext) { AttributeDispatchContext adc = (AttributeDispatchContext) lookup; result = adc.get(property); } return info != null ? info.convertValue(result) : result; }
