Java三元运算符与if/else在JDK8兼容性方面的区别

最近我在阅读Spring Framework的源代码。有一些我不理解的内容如下：

public Member getMember() {
    // NOTE: no ternary expression to retain JDK <8 compatibility even when using
    // the JDK 8 compiler (potentially selecting java.lang.reflect.Executable
    // as common type, with that new base class not available on older JDKs)
    if (this.method != null) {
        return this.method;
    }
    else {
        return this.constructor;
    }
}

这个方法是org.springframework.core.MethodParameter类的成员。代码很容易理解，而注释很难懂。

NOTE: no ternary expression to retain JDK <8 compatibility even when using the JDK 8 compiler (potentially selecting java.lang.reflect.Executable as common type, with that new base class not available on older JDKs)

在这个上下文中，使用三元表达式和使用if...else...结构有什么区别？
