Description

The following code produces a NPE, a more descriptive exception (and exception message) would be helpful.

ServletFileUpload upload = new ServletFileUpload();
try {
List<FileItem> items = upload.parseRequest(request);
/* ... */
} catch (Exception e) {
e.printStackTrace();
}

The exception is:
java.lang.NullPointerException
