33  * InvocationInfo caches various attributes of the method that
34  * is currently held in the invocation object (that is currently executed)
35  * This avoids some of the expensive operations like (for example)
36  * method.getName().startsWith("findByPrimaryKey")
37  *
38  * Every container maintains a HashMap of method VS invocationInfo that
39  * is populated during container initialization
