Javap ignores default modifier on interfaces

ADDITIONAL SYSTEM INFORMATION :
linux 64 bit

A DESCRIPTION OF THE PROBLEM :
Interfaces can have default implementation. javap -p ignores this modifier while dumping out interfaces.

Example:

javap -p "java.util.Comparator"
Compiled from "Comparator.java"

  public abstract int compare(T, T);
