recursive WEB-INF directories?

Hi Guys,
My web resource is pointed at /PROJECT-DIR/src/jsp
where a WEB-INF is created.
But each time I rebuild the project I get a recursive WEB-INF dir under the last WEB-INF/classes.

Can anyone tell me why, please?

Eventually, IDEA crashes on the cache directory - too many levels, no doubt.
