Remove blank lines before the xml directive. Most of the servlets add one or two blank lines before the xml directive. The xml directive should be first in a well-formed xml document. This patch sets the "trim-directive-whitespaces" property in the deployment descriptor, so that blank lines inserted by JSP directives are removed. The deployment descriptor format was upgraded from 2.3 to 2.5 in order to support this property.
