I can't really think of how null ends up in the resulting list, but adding a check in Iterator to detect that situation.

Also, improved the efficiency of the subList implementation.

Added uninstaller that removes *.jpi.

The only time whitespace contains the version number is when it's a private build, and they tend to be long.

So it's better to wrap this to maximize the width allocated to the description.

still not really sure what's causing this, so adding more probes. Those who are seeing this problem, please run this build and send us the message you see.

I tightened up the assertion pivot<=hi to pivot<hi, because lo<hi.

Thanks to newenigma for catching.

Clearly state that FingerprintAction, not UpstreamCause, is used for all upstream/downstream methods in this class (contrary to what you might expect).

Lots left untested—*fingerprint* and so on.
