NullPointerException in MessaageProperties.equals

[dmoses48]

org/springframework/amqp/core/MessageProperties.java equals method uses a non null-safe equals.

Example Test:

    MessageProperties mp = new MessageProperties();
    MessageProperties mp2 = new MessageProperties();
    mp.equals(mp2);  //Throws null pointer exception

Confirmed. This happens on the path:

if (!this.correlationId.equals(other.correlationId)) {
	return false;
}

We have to protect there like:

if (this.correlationId == null) {
	if (other.correlationId != null) {
		return false;
	}
}
