JSP Issue in 9.1 but not 8.1

Question

I am building a Web application and packaging it into an EAR file then deploying it into 9.1 WebLogic server. I have an issue that is happening when I activate the changes at deployment time but this one is when it's trying to compile the JSP code, as follows:
          -- cut --
          Substituted for the exception weblogic.servlet.jsp.CompilationException which lacks a String contructor, original message - wi_marital_status_coapp_us_en.inc.jsp:53:2: This tag is not recognized. <jsp:usebean id="userBean" ^---------^ wi_marital_status_coapp_us_en.inc.jsp:61:2: This tag is not recognized. ><jsp:usebean id="errorBean" ^---------^ wi_marital_status_coapp_us_en.inc.jsp:69:2: This tag is not recognized. ><jsp:usebean id="creditAppBean" ^---------^ wi_marital_status_coapp_us_en.inc.jsp:79:35: The qualifier of this name is a package, which cannot contain methods. ><util:If predicate="<%= !userBean.isAuthenticated() %>" > ^-------------^ wi_marital_status_coapp_us_en.inc.jsp:87:25: No match was found for method size() in type <error>. <util:If predicate="<%= creditAppBean.getData().size() == 0 %>"> ^----------------------------^ wi_marital_status_coapp_us_en.inc.jsp:87:39: The qualifier of this name is a package, which cannot contain methods. <util:If predicate="<%= creditAppBean.getData().size() == 0 %>"> ^-----^ wi_marital_status_coapp_us_en.inc.jsp:95:32: The qualifier of this name is a package, which cannot contain methods. <% Set errorFields = errorBean.getMessageFields(); %> ^--------------^
          -- cut --
          It seems to be complaining about it in 9.1 but not in 8.1.
          Please advise.
          Thanks,
