大致出现的问题如下
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (c1_Optimizer.cpp:271), pid=1196, tid=4412
# guarantee(x_compare_res != Constant::not_comparable) failed: incomparable constants in IfOp

原因是：JIT在做编译优化的时候处理 某个方法时出错。
如何知道自己哪个方法编译出错？
错误输出中会告诉你错误日志文件地址，如上：D:\Program Files\eclipse-jee-oxygen-R-win32\eclipse\hs_err_pid9188.log
打开日志文件，THREAD输出下会有具体错误的Java类和方法，本例中内容为：
Current CompileTask:
C1: 20924 1686 org.hibernate.cfg.annotations.SimpleValueBinder.setType
(Lorg/hibernate/annotations/common/reflection/XProperty;Lorg/hibernate/annotations/common/reflection/XClass;)V (921 bytes)
问题就出在org.hibernate.cfg.annotations.SimpleValueBinder.setType 编译出问题
解决办法
让jvm跳过该方法的编译
jvm启动添加如下参数
-XX:CompileCommand=exclude,org/hibernate/cfg/annotations/SimpleValueBinder，setType
如果是tomcat直接启动，在可以在/bin/catalina.bat添加如下参数
set JAVA_OPTS=%JAVA_OPTS% -XX:CompileCommand=exclude,org/hibernate/cfg/annotations/SimpleValueBinder,setType %LOGGING_CONFIG%
