* <p>Invokes an operation on an MBean.</p>

* through an {@linkplain JMX#newMBeanProxy(MBeanServerConnection, ObjectName,
* Class) MBean proxy} where possible. For example, suppose you have a
* Standard MBean interface like this:</p>
*
* <pre>
* public interface FooMBean {
* public int countMatches(String[] patterns, boolean ignoreCase);
* }
* </pre>
*
* <p>The {@code countMatches} operation can be invoked as follows:</p>
*
* <pre>
* String[] myPatterns = ...;
* int count = (Integer) mbeanServerConnection.invoke(
* objectName,
* "countMatches",
* new Object[] {myPatterns, true},
* new String[] {String[].class.getName(), boolean.class.getName()});
* </pre>
*
* <p>Alternatively, it can be invoked through a proxy as follows:</p>
*
* <pre>
* String[] myPatterns = ...;
* FooMBean fooProxy = JMX.newMBeanProxy(
* mbeanServerConnection, objectName, FooMBean.class);
* int count = fooProxy.countMatches(myPatterns, true);
* </pre>
*

* class loader as the one used for loading the MBean on which the
* operation was invoked.
*
