Summary:  Race condition in ClassType.java and cxr.java

Original Submission:  There are two race conditions that I'm seeing when 
running under heavy multi-threaded scenarios.

In ClassType.java we have a few test/set blocks that need a syncronized block 
around them.  For example:
  public Method getDeclaredMethods()
  {
    if ((flags & (ADD_METHODS_DONE|EXISTING_CLASS)) == EXISTING_CLASS)
      addMethods(getReflectClass());
    return methods;
  }

A similar situation exists in cxr.java:
 public Object apply1 (Object arg1)
  {
    if (count == 0)
      program(getName().toString());
   ...

I can provide patches if you'de like.
