I'll start with a class in the jdk package :
public final class Sdp {
should be :
public final class SocketsDirectProtocol {
Sdp is class name, this is ambigious, should be :
Class<?> cl = Class.forName("
java.net.SdpSocketImpl", true, null);
should be :
Class<?> clazz = Class.forName("
java.net.SdpSocketImpl", true, null);
cl is ambiguous
private static void setAccessible(final AccessibleObject o) {
should be :
private static void setAccessible(final AccessibleObject accessibleObject) {
There are various other examples in this class, do you have similar and/or differing examples of variables that were named badly ?
package com.oracle.net;
public final class Sdp {
private Sdp() { }
