Last night we upgraded our JVM from 1.4 to 1.5. After the upgrade, the
server still works, however we're getting an exception thrown repeatedly:

- Error unregistering mbean
javax.management.RuntimeOperationsException: Object name cannot be null
at com.sun.jmx.mbeanserver.JmxMBeanServer.isRegistered(
at org.apache.commons.modeler.Registry.unregisterComponent(

Caused by: java.lang.IllegalArgumentException: Object name cannot be null

We're running Tomcat 5.0, Apache 2.0 with jk_mod against a sybase db. The
only change was the JVM and our webapp compiled in 1.5. Any ideas where to
start looking???
