构建Sencha/ExtJS 5项目时出现java.lang.StackOverflowError

Question

当我打开我的项目并且Eclipse尝试构建它时，我收到了这个错误：在“构建工作区”期间发生了一个内部错误。java.lang.StackOverflowError.

它仍然完成构建（我想），我可以继续。但是我收到一个“内部错误”弹出窗口，说发生了堆栈溢出，建议我退出工作台。我只是忽略了弹出窗口。

以下是我的.log输出：

我该怎么做才能避免这个问题？

Answer 1

如何处理StackOverflow错误：

最简单的解决方案是仔细检查堆栈跟踪并检测行号的重复模式。这些行号表示递归调用的代码。一旦检测到这些行，就必须仔细检查代码并理解递归从未终止的原因。

如果您已经验证了递归的正确实现，那么您可以增加堆栈的大小，以便允许更多的调用。根据安装的Java虚拟机(JVM ),默认线程堆栈大小可能等于512KB或1MB。您可以使用-Xss标志增加线程堆栈的大小。可以通过项目的配置或命令行来指定此标志。< code>-Xss参数的格式为:

-Xss<size>[g|G|m|M|k|K]

顺便说一句，这似乎是一个日食错误（阅读此引用），已在最新版本中修复。

JstMixedType似乎会累积多个类型并连接它们的名称。在您的情况下，它包含自己（或围绕自己的代理，确切地说）。这不应该发生。这似乎是VJET核心中的一个错误，应该报告。

也许你可以通过修改你的配置/代码来解决这个问题。你有包含他们自己的任何混合类型吗？这是有意的吗？(很可能是)如果不是，就把它们换掉。
