7.2.10 SecondConstantPool Attribute

This attribute represents the second constant pool, containing all names and types that appear in the specification part of the class description. It has the following structure:

     SecondConstantPool_attribute {
       u2 attribute_name_index;
       u4 attribute_length;
       u2 second_cp_count;
       cp_info second_cp[second_cp_count];
     }

The meaning of the fields is as follows:

• attribute_name_index - index in the constant pool of the attribute name (org.bmlspecs.SecondConstantPool)
• attribute_length - length in bytes of the whole structure
• second_cp_count - the number of entries in the second constant pool
• second_cp - an array of cp_info structures, as described in Constant Pool.

The structure of this attribute closely resembles the definition of the JVM constant pool structure. If a JVM constant pool is of size cp_count, then all references #n with n smaller than cp_count are references to the JVM constant pool, and references #n with n greater or equal than cp_count are references to a field in the second constant pool with index n-cp_count. References #n with n greater or equal to cp_count+second_cp_count are invalid. This attribute can occur only once.
