Any idea what would cause this error? class not found: java.lang.management.managementFactory

Hi Ed, I was trying to download the cfwatcher 2.1 release, but after downloading it, the attempt to open fails saying it's an invalid zip file. Any thoughts?
I do list the tool in my tools list, at http://www.cf411.com/#debug.

Hey, for what it's worth, I think I found the solution: it fails to come down in Chrome, but it works fine in Firefox. Very odd. Now, I realize that it may seem to some that this may be some setup problem in my config of Chrome, but I'll just point out that I download and open zip files all the time, so there does seem to be something about this file here that conflicts uniquely.
I don't see a ready solution, but I'll just share this for others to consider. Ed, you may want to consider adding a comment on the downloads page that if people have a problem and are using Chrome, to try something else. Totally your call, of course.
BTW, one other oddity: I never got an email indicating that you'd offered this reply. The strange thing is that I DID get an email notice about my first post itself (which was odd, as most blog tools don't notify you about your own initial comment). I have searched my entire inbox and folders (including spam folders), to no avail.
Again, just saying this in case you ever hear of anyone else saying they don't get a comment email. Could have just been a flat tire happening anywhere along the info superhighway. :-)
I'll go check out the new version of the watcher tool. Thanks again for it.
