Severity: normal

The openjdk package doesn't use the DH sequencer and didn't benefit
from the addition of dh_strip_nondeterminism in the build sequence
in debhelper/9.20151004.

Inserting a call to dh_strip_nondeterminism in the build would fix
several reproducibility issues, such as the entries order and timestamp
in the jar and jmod files, or the permissions in the src.zip files.

The call to dh_strip_nondeterminism can be inserted between dh_link
and dh_compress:
