今天更新代码之后，突然出现一个问题：Tomcat启动时，总是会出现jvm fatal error错误导致tomcat无法正常启动，以下是错误信息：

在网上搜寻好久，终于找到了类似错误，网上解释归结于：JIT在做编译优化的时候处理时出错，可能是触发了JVM的编译器的BUG导致的。幸好SUN（Oracle）提供了相关的文档说明，得以让我们解决了这个问题。 
文档地址： http://www.oracle.com/technetwork/java/javase/crashes-137240.html#gbyzu 

在这里，导致本次错误的是这个方法：

org.hibernate.cfg.annotations.SimpleValueBinder.setType

解决办法：让jvm跳过该方法的编译优化 

1.如果是eclipse下启动服务，则在myeclipse-preference-java-installed jres 里面设置， 在 defalt vm arguments 填入下边的代码就可以了！如图：

代码：

	-XX:CompileCommand=exclude,org/hibernate/cfg/annotations/SimpleValueBinder,setType

 

选择使用的JRE,，点击编辑edit

将上边代码粘贴到此处，OK

2.如果是直接通过startup 启动tomcat，则需要修改以下文件 Windows下，在文件/bin/catalina.bat，Unix下，在文件/bin/catalina.sh找到

	set JAVA_OPTS=%JAVA_OPTS%  %LOGGING_CONFIG%  

修改为以下内容即可：

	set JAVA_OPTS=%JAVA_OPTS% -XX:CompileCommand=exclude,org/hibernate/cfg/annotations/SimpleValueBinder,setType %LOGGING_CONFIG%  

如图：
