[Felix Lechner <felix.lechner@lease-up.com>]

Hi,

On Lintian master (which includes the pending commit) and with
default-jdk 2:1.11-70 and javahelper 0.71 installed, I get

If the existing tags are correct, what would a good version
requirement look like for Extra-Build-Depends: in 'desc', please?
Thank you!
