Java 8 Nashorn ArrayIndexOutOfBoundsException
问题描述:
如果有什么,我能做些什么来阻止Nashorn始终抛出ArrayIndexOutOfBoundsException?Java 8 Nashorn ArrayIndexOutOfBoundsException
这个看似微不足道的,正确的(有没有错误本文中)的代码片段导致犀牛的例外:
文件test.js:
var test;
(function (test) {
(function (renderer) {
var posts = {
0: null,
1: null,
2: null,
3: null // comment out this line --> no exception thrown
};
})(test.renderer = {}); // comment out 'test.renderer = ' --> no exception thrown
})(test = {});
然后运行该脚本,像这样:/usr/lib/jvm/java-8-oracle/bin/jjs test.js
结果:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4

当我通过脚本引擎从JVM中运行文件时,也会发生这种情况。
背景:我试图在Nashorn中运行TypeScript生成的代码。上面的代码片段是简化的TypeScript编译器输出。
操作系统:Linux Mint 17,64位。 Java版本:
$ java -version
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
答
显然这是Java 8中的一个错误。我发布到Nashorn邮件列表;这里是回复:
I can reproduce the problem with 8u20, however it seems to be fixed in
JDK 9 and JDK8u40. You can download a preview release of 8u40 here:
https://jdk8.java.net/download.html
电子邮件:http://mail.openjdk.java.net/pipermail/nashorn-dev/2014-October/003614.html
(编辑:还有另一个的ArrayIndexOutOfBounds错误8u40,在这里阅读更多:http://mail.openjdk.java.net/pipermail/nashorn-dev/2015-March/004268.html“无法解析JSON:{0:空, 100:null}“。该问题已在8u60中修复。)
您可以发布java -version的输出吗?我注意到Nashorn正在改变JDK 1.8的各种小版本,所以它可能会有所作为。 – 2014-10-04 11:33:41
@ DavidP.Caldwell是的,我忘了,完成了(附加到问题)。 – KajMagnus 2014-10-05 05:10:00
嗨@Jarrod Robertson,实际上这不是http://stackoverflow.com/questions/32568261/how-to-avoid-java-lang-arrayindexoutofboundsexception的重复。这个问题是关于Nashorn *总是抛出'ArrayIndexOutOfBoundsException',即使是*正确的*代码 - 原因是Nashorn中的错误。 – KajMagnus 2016-03-04 03:21:59
