            Reporter: Hiroko Miura

compilation fails with the following DRL.

{noformat}
package com.sample;
//generated from Decision Table
import com.sample.Message;
// rule values at C11, header at C6
rule "HelloWorldXLS_11"
	when
		m:Message(status == Message.HELLO)
	then
		System.out.println(m.getMsg());
		m.setMsg("Goodbye cruel world");update(m);
		m.setStatus(Message.GOODBYE);update(m);
end

// rule values at C12, header at C6
rule "HelloWorldXLS_12"
	when
		m:Message(status == Message.GOODBYE)
	then
		System.out.println(m.getMsg());
end
{noformat}

Here is an ERROR.

                                                                                            (_this) -> _this.getStatus() == Message.HELLO,
                                                                                            D.reactOn("status")),
                                                                      D.on(var_m).execute((drools, m) -> {
            System.out.println(m.getMsg());
            m.setMsg("Goodbye cruel world");
            drools.update(m,
                          mask_m);
            m.setStatus(Message.GOODBYE);
            drools.update(m,
                          mask_m);
        }));
        return rule;
    }
{noformat}

If first update() (which is just after m.setMsg()) is removed, compilation works.
