RegTest-test java/nio/channels/Selector/SelectorTest.java test fails with JDK1.4.2-b16
on Solaris 8 sparc, Solaris 9 sparc, Solaris 8 x86 one time from three approximatelly.
The test throws the following exceptions:

I am not able to reproduce the failure on my RedHat Linux and Windows systems.

Probably this is a threads synchronization problem. The test always passes
on all platforms if I add "Thread.sleep(1000)" command before line 322 in SelectorTest.java:
...
319> try {
320> while(connectionsHandled < SelectorTest.NUM_CLIENTS) {

                    Thread.sleep(1000);

321> int numKeys = selector.select(100);
322>
323> // Process channels with data
324> synchronized (nKeys) {
...
