Decoder represents a jdk ClassFile header. See "The Java Virtual Machine Specification"
for a detailed description of all of the fields in this and other classes in this
package and the "cp" (constant pool) package
<p>
Basically, all of the other classes hold indexes into one of the fields in this
class. Cp classes hold indexes into the constant_pool, which holds all of the Cp
instances associated with this CompiledClass. A CpMethodref, for instance, holds an
index into the constant_pool to locate the CpClass implementing the method as well
as an index into the constant_pool of the CpNameAndType of the method itself.
