Web Services tests do not compile correctly because the code was not maintained. Even if compilable, the tests might not have good coverage for the functionality.
The whole webservices stuff is not really portable, as it makes an assumption about the location of javac or rt.jar (forgot what exactly) being in /usr/bin and that this directory is writable. This is at least not true on OS X and I would not expect /usr being writable for everyone on other Linux or Unix systems as well.
No longer applicable.
