Tomcat启动:A fatal error has been detected by the Java Runtime Environment（JVM Crash分析及相关资料）
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。

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