       Body:
On 2nd check, this patch does seem to work.  The NPE was caused by recompiling and not 
including the new xdoclet-xdoclet-module-version.jar.  If there are no objections, I'd 
like to check this in.  I've tested it with Ant 1.6.2 and Ant 1.5.4.  

The error seems to occur when you try to run an XDoclet task twice in the same Ant 
execution.

Environment: Windows XP, JDK 1.4.2, Ant 1.6.1

Description:
When I do an "ant clean" and try to run "webdoclet" on my project, I get the following 
error:

"destDir attribute must be present."

According to the following Ant bug report:

It is a bug in the xdoclet code.
At the end of the execute method, it cleans up (nulls)
some internal variables. This code also incorrectly nulls the
destdir attribute.

I'll attach a patch that seems to fix this problem.  Note that it only happens when I 
do a clean checkout and the first build on my project.
