* Unit test to ensure that servlet that was generated from JSP is reloaded
* when its class file is updated (without the JSP getting recompiled).
*
* This unit test accesses a JSP, which causes the JSP to be compiled to a
* servlet, and the servlet class to be loaded. The unit test checks the
* servlet response and makes sure it matches the expected output ("This is
* my output").
*
* The test then updates the servlet class file (without recompiling the
* JSP!). The updated servlet class file generates a different output ("This
* is my UPDATED output") than the original class file. The unit test checks
* that the servlet is reloaded (by comparing its output against the expected
* modified output) the next time the JSP is accessed.
