/**
 * The RuntimeInvisibleAnnotations attribute is similar to the
 * RuntimeVisibleAnnotations attribute, except that the annotations represented by
 * a RuntimeInvisibleAnnotations attribute must not be made available for return
 * by reflective APIs, unless the JVM has been instructed to retain these
 * annotations via some implementation-specific mechanism such as a command line
 * flag. In the absence of such instructions, the JVM ignores this attribute.
 * 

* The RuntimeInvisibleAnnotations attribute is a variable length attribute in the * attributes table of the ClassFile, field_info, and method_info structures. The * RuntimeInvisibleAnnotations attribute records runtime-invisible Java * programming language annotations on the corresponding class, method, or field. * Each ClassFile, field_info, and method_info structure may contain at most one * RuntimeInvisibleAnnotations attribute, which records all the runtime-invisible * Java programming language annotations on the corresponding program element. *

* The RuntimeInvisibleAnnotations attribute has the following format: *

 *   RuntimeInvisibleAnnotations_attribute {
 *     u2 attribute_name_index;
 *     u4 attribute_length;
 *     u2 num_annotations;
 *     annotation annotations[num_annotations];
 *   }
 * 
* The items of the RuntimeInvisibleAnnotations structure are as follows: *
*
attribute_name_index
*
The value of the attribute_name_index item must be a valid index into the * constant_pool table. The constant_pool entry at that index must be a * CONSTANT_Utf8_info structure representing the string * "RuntimeInvisibleAnnotations".
*
attribute_length
*
The value of the attribute_length item indicates the length of the * attribute, excluding the initial six bytes. The value of the * attribute_length item is thus dependent on the number of runtime-invisible * annotations represented by the structure, and their values.
*
num_annotations
*
The value of the num_annotations item gives the number of runtime-invisible * annotations represented by the structure. Note that a maximum of 65535 * runtime-invisible Java programming language annotations may be directly * attached to a program element.
*
annotations
*
Each value of the annotations table represents a single runtime-invisible * {@link oracle.toplink.libraries.asm.attrs.Annotation annotation} on a program element.
