Description

The org.apache.uima.aae.controller.UimacppServiceManagement class implements the service MBean, which reports JMX statistics of UIMA-CPP engines. Some of the 'get...()' methods of this class modify the state of the class instance, other 'get...()' methods access modified instance variables. To ensure proper access to JMX statistics of UIMA-CPP engines, all the 'get...()' methods of this class need to be synchronized.
