Using setMaxPriority() method, user can decrease group priority,
but cannot increase it, even to the previous value.

Such behaviour contradicts the specification.
 
------------------------------------- file setMaxPriority0102.java
// simplified version of the test
// javasoft.sqe.tests.api.java.lang.ThreadGroup.setMaxPriority0102;

import java.io.PrintStream;

public class setMaxPriority0102 {

  public static void main(String args[]) {
	ThreadGroup group=new ThreadGroup("setMaxPriority0102");

	for (int prio=Thread.MIN_PRIORITY; prio<=Thread.MAX_PRIORITY; prio++) {
		try {
			group.setMaxPriority(prio);

			prio1=group.getMaxPriority();
		} catch (Throwable e) {
			System.out.println("unexpected exception in setMaxPriority("+prio+"):"+e);
			return;

		if (prio1!=prio) {
			System.out.println("setMaxPriority("+prio+"); getMaxPriority()="+prio1);

Running the test:
novo64% javac setMaxPriority0102.java
novo64% setenv CLASSPATH .
novo64% java setMaxPriority0102
setMaxPriority(2); getMaxPriority()=1
novo64%
