pmd: remove unused private method
pmd: don't create instances of existing BigInteger
pmd: avoid empty if statements
suppress the deprecation warnings

Removed 2 of the System.out.printlns but we need to remove a lot
more.
pmd: don't use fully qualified package when not needed

It's funny but pmd actually reported the error to AvoidThreadGroup but I found
java.util.LinkedList. At least pmd was consistently wrong :D
pmd: remove useless @Override
pmd: remove unused private fields
pmd: remove unused local variables
pmd: remove unused formal parameters

Avoid passing parameters to methods or constructors and then not using those
parameters.

public class Foo {
 private void bar(String howdy) {
   // howdy is not used
 }
pmd: Avoid unnecessary temps when converting primatives
pmd: remove unused imports
