#jdk1.7排序时异常 java.lang.IllegalArgumentException: Comparis

本文解决本地Eclipse和服务器Tomcat中遇到的Java.lang.IllegalArgumentException错误，通过调整JVM参数避免使用默认的TimSort排序算法，继续采用Java 1.6的排序方式。

java.lang.IllegalArgumentException: Comparison method violates its general contract

解决方案：

-Djava.util.Arrays.useLegacyMergeSort=true

本机eclipse  jvm参数设置可解决本机问题。

服务器 tomcat 修改JAVA_OPTS参数增加该句可以解决

 

加入该句代表继续采用jdk1.6的排序方式，jdk1.7中将TimSort作为排序的默认实现

通过List.sort对元素进行排序，测试阶段没发现，在st测试的时候报了这个错误。“Comparison method violates its general contract!”。 具体堆栈信息： 看起来没什么问题，但是却报了一个错，“比较方法违反其一般合同”。 在 JDK7 版本以上，Comparator 要满足自反性，传递性，对称性，不然 Arrays.sort，Collections.sort会报 IllegalArgumentException 异常。 自反性：当 两个相同的元素.

表示你的比较器（Comparator）违反了其一般约定。能表示的最大值（即 Integer.MAX_VALUE 或者说 2^31 - 1），就会发生整型溢出，导致比较结果不准确。相减时可能会得到负数，而这个负数可能并不代表逻辑上的“小于”。方法，它避免了整型溢出的问题，并且正确地实现了比较逻辑。，其次使用安全的比较方法。代码这样的，其中startTime是时间戳。类型，那么就不会有溢出的风险，而且。可能会导致溢出问题。方法中整型溢出的处理上。改进的方法是，首先不要强制将。时，如果时间戳值超过。
