jessie: Problems upgrading openjdk-7-jdk with openjdk-7-source installed

[Felix Natter <fnatter@gmx.net>]

hello,

I get this:

E: Sub-process /usr/bin/dpkg returned an error code (1)

when running apt-get dist-upgrade today on jessie.

The upgrade works fine when I remove openjdk-7-source.  --> I do think
that this should be handled more gracefully, as this leads to a broken
upgrade which leads to the current kernel not booting, but I guess it's
solved in unstable anyway ;-)

Thanks and Best Regards,
