Live image build (Debian Junior) is not working (ca-certificates-java)

Hello,

the weekly build for Debian Junior has not been generated this
week.

I tried the live image build on my local system. The build is
currently not working. On my local system the build hangs on
dpkg-reconfigure of ca-certificates-java (postinstal script ->
calls java -version).

Maybe it's the reason why the build was not possible this week.
