Pax Web and Felix 4.0.1

[Markus Dippold <di...@googlemail.com>]

Hi,

we tried to upgrade Felix from 3.2.2 to 4.0.1 and we are using Pax Web
1.0.7.
It works as expected, but every time we shut down the framework, Pax Web
throws an exception:

The exception has no negative effects, but it just does not look good.

Can anybody help us to avoid this exception?

Best regards,
Markus
