Several threads waiting in org.apache.activemq.broker.jmx.ManagementContext.registerMBean/unregisterMBean

Hi,
     We are using ActiveMQ 5.7.0 in OSGi container running on JDK 7. We recently migrated from ActiveMQ 5.5.1 to 5.7.0. There are no issues with 5.5.1. After after migration there are several (around 80) threads like below waiting for registerMBean or unregisterMBean. Any reason for this weird behavior?
