The documentation may give the impression that you can set the value of the=
 threadPriority attribute to a string referring to some static field, but t=
hat is not actually the case.  You must supply a numeric value here, which =
will normally be 10 for the maximum.  You can write a simple Java program t=
o display the values of Thread.MIN_PRIORITY and Thread.MAX_PRIORITY, and ch=
oose a number within that range.

class ThreadPriority {
  static public void main(String args[]) throws Exception {
    System.out.format("thread priorities: MIN %d, NORM %d, MAX %d%n",
                      Thread.MIN_PRIORITY, Thread.MIN_PRIORITY, Thread.MAX_=
PRIORITY);
  }
}

The JDK 7 Javadoc includes a description for the priority values, but it do=
esn't appear to be completely accurate:
http://docs.oracle.com/javase/7/docs/api/constant-values.html#java.lang.Thr=
ead.MAX_PRIORITY
