Jitsi build-depends on openjdk-7-jre but the package fails to install in pbuilder and thus I currently cannot build the package. Here's is the output I get while I am logged in to the trusty chroot.

# aptitude install default-jdk
[...]
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:
