am trying one of example CoAP server program from Californium Github source file HelloWorldServer.java

I have used library californium-core-1.0.1.jar file

When I run below code to addEndpoints, I get an exception:

private void addEndpoints() {
for (InetAddress addr : EndpointManager.getEndpointManager().getNetworkInterfaces()) {
// only binds to IPv4 addresses and localhost
if (addr instanceof Inet4Address || addr.isLoopbackAddress()) {
System.out.println("addr: "+addr.toString());
InetSocketAddress bindToAddress = new InetSocketAddress(addr, COAP_PORT);
System.out.println("bindToAddress: "+bindToAddress.toString());
addEndpoint(new CoapEndpoint(bindToAddress));
}
}
}
Here is the Exception:

Jan 20, 2016 3:24:58 PM org.eclipse.californium.core.network.config.NetworkConfig createStandardWithFile INFO: Storing standard properties in file Californium.properties

addr: /127.0.0.1 bindToAddress: /127.0.0.1:5683

I tried to clean and rebuild the project still same issue. Created project again, don't work

I see no file in GitHub Source org/eclipse/californium/elements/RawDataChannel.java is that is the problem !?

Thanks in advance
