openjdk-lts (11.0.1+13-3ubuntu2) disco; urgency=medium

  * debian/buildwatch.sh: use same code from openjdk-8.
  * debian/control.in, debian/control:
    - add fixed build depends for jtreg and xfvb.
  * debian/rules:
    - call the same testsuites scripts used for autopkgtest.
    - removed jtreg and xvfb build dependency logic and moved the bdeps
      into debian/control.in.
    - added gen-autopackage rule to generate autopkgtest scripts from
      templates.
    - copy flight recorder configuration files.
    - fix logging in langtools testing.
    - don't ignore/exclude the release file from the jdk package, it is
      required by jtreg tests and autopkgtests will fail without it.
    - don't run nashorn testsuite.
    - add prune-build-dir rule to cleanup build dir from unnecessary
      files.

      debian/tests/langtools: use the new jt .sh scripts.
    - debian/tests/jtdiff-autopkgtest.sh: used by the scripts to report
      any differences between the autopkgtest and the tests results
      generated during the openjdk package build.
    - debian/tests/jtreg-autopkgtest.in: template to generate the jtreg
      script used by the autopkgtest tests.
    - debian/tests/jtreg-autopkgtest.sh: used by the scripts to run jtreg
      and put the resulting artifacts in the right places.
    - debian/tests/hotspot, debian/tests/jaxp, debian/tests/jdk,
      debian/tests/langtools: run same testsuites as build time and
      compare the results.
    - debian/tests/valid-tests: no longer needed, removed.
