resolveConstPool

readConstPool

private void readConstPool(java.io.DataInputStream dStream)

Read the JVM class file constant pool and put it in the internal constant pool.

There is a special case in constant pool construction. CONSTANT_Long_info and CONSTANT_Double_info structures take up tow elements in the constant pool table (constPool). See JVM Spec. 4.4.5. As noted in a footnote "In retrospect, making 8-byte constants take two constant pool entries was a poor choice." The extra constant pool entry is unused (and is set to null here).
