Occasionally we are seeing a security warning when starting a WebStart application on Java 7. The warning is about an expired certificate ("digital signature has expired").

When looking at details offered by the dialog, the certificate period is not expired, actually. At the time of this writing, the certificate was recently renewed and starts about a week in the past, and ends in two years.

First I thought that this might be caused by not signing the JNLP itself because the the security details warn about an unsigned JNLP:

Furthermore, this post seems to indicate that JNLP signing might be mandatory:

The JNLP spec describes this as optional. What else could be the problem here?
