Bug#797659: openjdk-6: please allow derivatives build as parent distro

[Hector Oron <zumbi@debian.org>]

Source: openjdk-6
Version: 6-6b36-1.13.8
Severity: wishlist

Hello,

  Please consider patching your package so derivative distributions are able
  to use same build runes as parent distribution.

Regards
