This failure occurs with Merlin b61 on windows platforms ( I tested with win98 , winNT and win2000 ).The same is passing with Merlin b60 on the above mentioned windows platforms.

With Merlin b61 this is passing on solaris 7 and solaris 8.


----- testcode ----------

try {
Selector selector = Selector.open() ;

java.nio.Pipe pipe = Pipe.open();
Pipe.SourceChannel channel = pipe.source();

// SocketChannel channel = SocketChannel.open() ;

// isRegistered() should return false for newly created channel
// since channel is not registered with any selector yet
if (channel.isRegistered() != false) {
return TestHelper.testFail(testName +
" FAIL : isRegistered() didn't return false for newly created channel ! " + channel.isRegistered()) ;

}

// now, blocking mode should change
channel.configureBlocking(false);

// bug#4424026
SelectionKey key = channel.register(selector,SelectionKey.OP_READ);
//SelectionKey key = channel.register(selector,SelectionKey.OP_ACCEPT);


// after registration, isRegistered() should return true
if (!channel.isRegistered()) {
return TestHelper.testFail(testName +
" FAIL : isRegistered() expected to return true ! ") ;

}

} catch (Exception e) {
return TestHelper.testFail(testName +
" FAIL : unexpected Exception !", e) ;
}
