Question

我有java class Fact，如下所示

class AssertionFact {
   String name;
   Object value;
}

当我使用Drools 5.2＆amp;规则如下，它工作得很好。

AssertionFact(
                                    object > 100,
                                    name == "testName"
                                )

但是现在当我将我的drools版本升级到6.4.0＆amp; JDK 1.8对于相同的规则，我的误差低于误差。

Caused by: java.lang.RuntimeException: uncomparable values <<TESTVALUE>> and <<100.0>>

Drools 6.4.0失败，错误无法比较
