 * Unit test for 6181949 ("JspServlet init param 'modificationTestInterval'
 * ignored").
 *
 * This test:
 * 
 *  - accesses a JSP,
 *
 *  - updates the JSP (through a servlet),
 *
 *  - accesses the JSP again within modificationTestInterval seconds (and
 *    therefore is expected to get the old contents), and
 *
 *  - accesses the JSP once again after modificationTestInterval seconds have
 *    expired (and therefore is expected to get the updated contents).
