java - Eclipse Xtext 作为应用程序运行 - Java 错误

Question

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

# JRE version: 7.0_04-b21
# Java VM: Java HotSpot(TM) 64-Bit Server VM (23.0-b21 mixed mode bsd-amd64 compressed oops)
# Problematic frame:
# J  org.eclipse.osgi.internal.resolver.VersionConstraintImpl.getName()Ljava/lang/String;
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

#
# If you would like to submit a bug report, please visit:

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，但没有任何效果。

有什么想法吗？

问题不在于 Xtext。它没有原生部件，不会产生这样的错误。恰好是这样，这个特定项目在 eclipse native 代码或(更有可能)JRE 或其他库 native 代码中触发错误。

为了解决这个问题，我建议如下:

将您的 JRE 升级到最新版本(第 7 版更新 17)

尝试来自其他供应商的 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

重新下载所有相关软件(JDK、eclipse 等)

检查项目中所有外部库的本地部件并升级/替换它

还有一个很小的可能性，即这是一个硬件问题。但是您可以通过尝试在不同的机器上运行您的项目来简单地解决它。
