如果我尝试使用日期类型条件的简单 Drools 规则并使用条件 OR ( ||)，则会收到以下错误。如果我改变||它&&工作正常。这是错误、已知限制还是我的规则有问题？我正在使用 Drools 5.5.0 Final

规则文件

package net.madhura.drools.rules

import net.madhura.drools.DateContainer;

dialect "mvel"

rule "Test rule"
when
    $container: DateContainer(
        date >= "15-Oct-2013" || date <= "01-Oct-2013"
    )
then
    System.out.println("working");
end

日期容器类

package net.madhura.drools;

import java.util.Date;

public class DateContainer {

    private Date date;

    public DateContainer(Date date) {
        this.date = date;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }
}

错误

Unable to Analyse Expression date >= "15-Oct-2013" || date <= "01-Oct-2013":
[Error: Comparison operation requires compatible types. Found class java.util.Date and class java.lang.String]
[Near : {... date >= "15-Oct-2013" || date <= "01-Oct-2013" ....}]
                                              ^
