             In both groups there is a specific type for each joinpoint type. The type of bean corresponding to each joinpoint type can be seen
             in <xref linkend="joinpointtypes"/>. All beans are in the package <literal>org.jboss.aop.joinpoint</literal>.

+               executions and calls, it refers to the object whose method is being executed (available only
+               on non-static methods). For field reads and writes, it refers to the object that contains that

+               whose method or constructor is performing the call (notice the caller object is not available if
