A fatal error has been detected by the Java Runtime Environment(jdk 1.6的一个BUG)

几天做项目，生成一堆注解的实体，当实体数超过86个时，jvm报错：

# # A fatal error has been detected by the Java Runtime Environment: # #  Internal Error (c1_Optimizer.cpp:271), pid=5104, tid=6488 #  guarantee(x_compare_res != Constant::not_comparable) failed: incomparable constants in IfOp # # JRE version: 6.0_35-b10 # Java VM: Java HotSpot(TM) Client VM (20.10-b01 mixed mode, sharing windows-x86 ) # An error report file with more information is saved as: # D:\开发工具\eclipse_up\hs_err_pid5104.log 20121130|13:44:09 [INFO ] [localhost-startStop-1] [AnnotationSessionFactoryBean:777] Building new Hibernate SessionFactory # # If you would like to submit a bug report, please visit: #   http://java.sun.com/webapps/bugreport/crash.jsp #

查询得知是windows版jdk 1.6bug(经测试,linux下无此问题),问题的原因就在于，JIT在做编译优化的时候处理 某个方法时出错。 错误是这个方法 

org.hibernate.cfg.annotations.SimpleValueBinder.setType  

解决办法：让jvm跳过该方法的编译优化 
在jvm启动参数中添加启动参数 

加入jvm启动参数：-XX:CompileCommand=exclude,org/hibernate/cfg/annotations/SimpleValueBinder.setType

或：换成jdk1.5  jdk7

 

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 

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