      1. Create one Jsp page and use jsp:include to include another page.
      2. For Page attribute, try providing combination of constant string with some variable.
        e.g. : <jsp:include page='ForwardFile.jsp?name=<%=temp%>' flush="true"/>

      Expected : it should work and page should be included.
      Actual : java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern - For input string: "=t"

      If we use scriptlet expression as below, it works fine:

      1. <jsp:include page='<%="ForwardFile.jsp?name="+temp%>' flush="true"/>
      2. <input type="text" name="j_<%=temp%>">

    Description

      When we use scriptlet expression in jsp:include tag for page attribute, it does not work when used partially.

      E.g. : <jsp:include page='ForwardFile.jsp?name=<%=temp%>' flush="true"/>

      Exception :
      java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern - For input string: "=t"

      It works in JBoss EAP 6.4.x release.
