com.alibaba.fastjson.util.TypeUtils 里的 catch AccessControlException 感觉要改为 Throwable，因为在jdk 17里抛出的异常是 java.lang.reflect.InaccessibleObjectException
static void setAccessible(AccessibleObject obj){
if(!setAccessibleEnable){
return;
}
if(obj.isAccessible()){
return;
}
try{
obj.setAccessible(true);
} catch(AccessControlException error){
setAccessibleEnable = false;
}
}
