我有一个 xtext 项目，我可以为它生成 xtext 工件，并使用 mwe2 生成器，但它不会作为 xtext 应用程序运行 - 给出错误：

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0xa) at pc=0x000000010ccc04d0, pid=4122, tid=38240796672

我可以运行另一个 xtext 项目，但不能运行这个。我为 JRE 系统库尝试了不同的设置，从头开始重建项目，但还没有任何效果。

有任何想法吗？

问题不在于 Xtext。它没有原生部分，也不会产生这样的错误。碰巧是这样，这个特定的项目在 eclipse 本机代码中或（更有可能）在 JRE 或其他库本机代码中触发错误。

为了解决这个问题，我建议如下：

  • 将您的 JRE 升级到最新的一些（版本 7 更新 17）
  • 尝试其他供应商的 JRE，例如 JRockit ( http://www.oracle.com/technetwork/middleware/jrockit/overview/index.html )
  • 将 Eclipse 升级到最新的错误修复版本
  • 重新下载了所有相关的软件（JDK，eclipse，...）
  • 检查项目中所有外部库的本地部分并升级/替换它

还有一个很小的可能性，这是一个硬件问题。但是您可以通过尝试在另一台机器上运行您的项目来简单地解决这个问题。
