应用访问中有些jsp页面无法显示,IE报错500，后台日志报错如下：

java.lang.ClassFormatError: jsp_servlet/_customermanage/__customerlist : illegal JVM_CONSTANT_Class name: [L[Ljava/lang/String;;.>

解决方法：

1.在MEM_ARGS中增加参数-Xverify:none

   -Xverify:<option>With no parameters, enables the verifier. Note that this is the default; used on its own, this option has no effect. 

   -Xverify:allThis option enables maximum verification. 

   -Xverify:noneThis option disables the verifier. 

   -Xverify:remoteThis option enables strict class-loading checks on remotely loaded classes.

2.如果还是没有解决，就要打补丁
