Canceled "Downloading Maven dependencies".

Comment 3 Jesse Glick 2011-04-05 22:25:05 UTC

The problem is that NB uses ThreadDeath as a signal that the download should terminate. If this happened in the calling thread, NB would quietly continue. But Aether uses a thread pool for downloads to increase I/O concurrency, and is not prepared to gracefully handle threads being killed.

Filed an upstream bug.
