Currently stalled due to lack of annotation support in cacao: Exception in thread "main" java.lang.UnsatisfiedLinkError: getDeclaredAnnotations at java.lang.Class.getDeclaredAnnotations(Class.java:1575) at java.lang.Class.getAnnotations(Class.java:1506) at java.lang.Class.getAnnotation(Class.java:1485) at javax.management.JMX.isMXBeanInterface(JMX.java:123) at javax.management.StandardMBean.<init>(StandardMBean.java:163) at gnu.javax.management.Server.getMBeanInfo(Server.java:1041) at gnu.classpath.examples.management.TestBeans.main(TestBeans.java:38)
CACAO needs --enable-annotations to enable the annotation support. With this, the example now works, so closing this bug.
