+1

This is part of the public java.util.Thread API. If those values change,
bad things likely happen.

From my Oracle Java 1.7 distro on 64-bit Mac OS:

    /**
     * The minimum priority that a thread can have.
     */
    public final static int MIN_PRIORITY = 1;

   /**
     * The default priority that is assigned to a thread.
     */
    public final static int NORM_PRIORITY = 5;

    /**
     * The maximum priority that a thread can have.
     */
    public final static int MAX_PRIORITY = 10;
