Eclipse中的Xtext作为应用程序运行 - Java错误

Question

我有一个XTEXT项目，我可以生成的XTEXT文物，并与mwe2发电机工作，但它不会运行作为XTEXT应用 - 让错误：

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

# 
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

我可以运行另一个xtext项目，但不是这一个。我已经尝试了JRE系统库的不同设置，从零开始重建了该项目，但没有任何工作。

任何想法？

的问题不是的Xtext。它没有本地部分，不能产生这样的错误。恰好如此，这个特定的项目在eclipse本地代码中触发错误，或者在JRE或其他库本机代码中触发错误（更可能）。

为了解决该问题，我建议如下：

• 升级JRE到最新的一些（第7版更新17）
• 尝试从其他供应商的JRE，喜欢的JRockit（http://www.oracle.com/technetwork/middleware/jrockit/overview/index.html）
• Eclipse的升级到最新的错误修复版本
• 重新下载所有相关软件（JDK，日食，...）
• 检查所有外国库项目中的原生看齐ts并升级/替换它

还有一个很小的可能性，这是一个硬件问题。但是你可以通过试图在不同的机器上运行你的项目来简化它的角色。
