【问题描述】：
我在 JDK 中遇到了一些内部错误（见下文）。由于此处引用了我自己的代码中没有任何行，因此我想检查原始代码中发生了什么。
在我的电脑上，我安装了JDK1.8.0_121。我只能在grepcode.com 上找到版本openjfx-78-backport 1.8.0-ea-b96.1，这在相关行似乎有所不同。
问题：（哪里）JDK1.8.0_121的源代码公开了？

【问题讨论】：
-
随 JDK 一起分发 - 查看 JDK 文件夹 src.zip
-
感谢您对 Jacek Cz 的评价。 - 我并不是说 JRE 中需要有错误。错误可能也在我这边。无论如何，要找到它，了解哪个列表导致此错误可能会有所帮助。例程
ListChangeListener$Change.getAddedSubList不是我自己实现或调用的。但我想了解他们正在处理哪些数据。这可能会提示我错误地初始化了哪个变量。 -
@6ton：找到了。谢谢！
-
你的代码是多线程的吗？您是否正在从 JavaFX 应用程序线程修改活动场景图的元素？如果是这样，有时会导致堆栈跟踪等问题（由于竞争条件）。
-
@jewelsea：我不会自己启动线程。在 TreeTableView 中更改选择时发生错误。停用我自己的一些听众会有所帮助，但我不明白为什么这个听众很重要。问题与以下内容有相似之处：stackoverflow.com/questions/27830075/… 无论如何我想更深入地了解发生了什么。
