LHS expression comparing a Boolean to a String does not fail but always returns true.

Example:
--------------------------------------------------------------------------------------------------------------------------
Modified the Drools HelloWorldExample and changed the status from an int to a boolean.

import org.drools.examples.HelloWorldExample.Message;
rule "Hello World"
    when
        m : Message( status == "hello", message : message )
    then
        System.out.println( message ); 
end

public static class Message {
        public static final boolean HELLO   = false;
        public static final boolean GOODBYE = true;
        private String message;
        private Boolean status;

        public Message() {}
        public String getMessage() { return this.message; }
        public void setMessage(final String message) { this.message = message; }
        public boolean getStatus() { return this.status; }
        public void setStatus(final boolean status) { this.status = status; }
}

final Message message = new Message();
message.setMessage( "Hello World" );
message.setStatus( Message.HELLO );
final StatefulSession session = ruleBase.newStatefulSession();
session.insert( message );
session.fireAllRules();
