Bug#861403: java-package: Package has dependency on libc6-amd64 if it is installed, but this can't be satisfied

[Joshua Honeycutt]

Package: java-package
Version: 0.62
Severity: normal

Dear Maintainer,

   I ran into user on IRC attempting to create a jre deb on an amd64
   system.

   They had an issue where their jre deb was depending on libc6-amd64
   which is an i386 arch package. The dependency could not be resolved
   so the resulting package was uninstallable. I think this is because
   dpkg was looking for a amd64 arch candidate. My system didn't
   produce this issue until I installed libc6-amd64 and ran
   java-package again.

   The user and I were able to produce packages with working depends if
   libc6-amd64 was removed. I'm not sure why it was installed on their
   system to begin with. #739758 seems to indicate it is undesireable
   for libc6-amd64 to be installed on amd64 systems.

   I was able to reproduce the issue on a jessie and stretch system.
