Reports any references to classes from the default package in JSP files.

Example:


  <%!
  Integer countSomeUsefulStuff() {
    ...
    new ClassFromDefaultPackage(...); // Error
    new com.example.GoodClass(...); // Good
  }
  %>
  <html>
    <head>
      <title>Hello, JSP!</title>
    </head>
  </html>

NOTE: Such references will not be resolved during compilation of the JSP because a compiled class for the JSP will be usually placed in non-default package (for example, "org.apache.jsp" in case of Tomcat, "com.ibm._jsp" in case of WebSphere), but importing from the default package is not allowed in Java.
