What do files deleted by groovy leave behind in Windows 7?
===

I have a groovy script that saves multiple files from a remote directory to my temp directory and parses them into xml.  It has an interesting bug.  Each time it runs, it can't find one file in my temp directory.  The next time it runs, it finds that file, but can't find a new file.  If I have 20 files, it won't find all 20 files until the 20th run.  The temp directory is cleared after each run.  I'm wondering if there are other artifacts the program is leaving behind?

If I clean the project after 16 runs, it still finds the first 16 files.  So it seems it's not an artifact in eclipse.

This is running in Eclipse 3, Java 1.5, Windows 7.
