Missing JSP in EAP 5.1.2.GA throwing file not found exception

Issue

The users are including a JSP which does not exist in the application and in 4.3 this seems to ignore the missing file but EAP 5.1.2.GA throws an exception shown below
This caused the following output to be renedered when I accessed the index.jsp file which contained the include line;

<jsp:include page="/missing.jsp"></jsp:include>
