Hi,
I'm developing using a Maven modular project (one module for the persistence
layer, another for the webapp) and using the maven-jetty plugin in
development.
However, I'm getting a strange error: when I make a change to the code jetty
(version 7.0.0) automatically restarts (as it should). However, it throws
the following error:

And it obviously fails restarting: I have to stop it and start it again.
Has any of you experienced something similar and/or knows why this is
happening?
Thank you,
Miguel
