Error description

While migrating an application running under WebLogic towards
WebSphere Application Server V8.5.5.10, we encounter an error
with certain JSP pages.

Here under the error stack:

[02/09/16 14:29:19:735 CEST] 00000091 ServletWrappe E
com.ibm.ws.
webcontainer.servlet.ServletWrapper service SRVE0068E:

Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server versions   *
*                  8.5.5, and 9.0 and Liberty                  *
****************************************************************
* PROBLEM DESCRIPTION: An Expression Language (EL)             *
*                      expression that processes the call      *
*                      of method isLast() of an object         *
*                      referencing the varStatus in a JSTL     *
*                      for-each tag, generates a               *
*                      java.lang.IllegalAccessException.       *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
If the JSP file below is run, the following exception will
be thrown:
javax.el.ELException: java.lang.IllegalAccessException: Class
javax.el.
BeanELResolver can not access a member of class
javax.servlet.jsp.jstl.
core.LoopTagSupport$1Status with modifiers "public"
JSP file generating the exception:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"
%>
<c:forEach items="${listOfValues}" var="entry"
varStatus="statusVarExample">
${statusVarExample.isLast()}
</c:forEach>
Where ${statusVarExample.isLast()} triggers the exception.

Problem conclusion

The EL code was modified to correctly call public methods
without throwing an exception.

The fix for this APAR is currently targeted for inclusion in
fix packs 8.0.0.13 and 8.5.5.12 for WebSphere Application
Server and 16.0.0.4 for WebSphere Application Server Liberty.
