Sample project to reproduce the issue
I have a bean which inherits an "is" prefixed boolean property from a package
private base class. I can get the property value using <jsp:getProperty>. But
if I try to get the value using expression language, I have the following
exception:
SEVERE: Servlet.service() for servlet [jsp] in context with path
[/JSPBeansTest] threw exception [javax.el.ELException:
java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access
a member of class user.UserBeanBase with modifiers "public"] with root cause

If the boolean property is in the base class and is prefixed with "get" its
value is retrieved without error.
