OpenJDK SRU exception

Fri Mar 23 22:34:49 UTC 2018

On behalf of the Ubuntu Foundations Team, I would like to provide
further information on the outstanding issues of the OpenJDK 9
transition.

Of the 35 direct reverse build and runtime dependencies of java-common
in Bionic/main, which amount to 26 source packages, there are 5 that
currently FTBFS when build with openjdk-9:
- gettext* (1001)
- db5.3 (130)
- apport* (28)
- brltty* (18)
- sonic* (6)

The number represents how many direct reverse build and runtime
dependencies each package has. An asterisk represents that there is a
known working patch.

Also gettext’s Debian bug #892733 might also require a fix as msgfmt
causes further packages to FTBFS.

The 2 important runtimes in Bionic/main are tomcat8 and libreoffice
(the database component) and both are run fine under OpenJDK 9. Let me
know if there is any particular use cases to try on those.

There are 171 packages - amounting to 97 source packages - that are a
direct reverse build or runtime dependency of maven in Bionic. Of
those there are 13 failures:
- maven-debian-helper (504)
- maven-bundle-plugin* (178)
- antlr3* (29)
- maven-enforcer (17)
- libxbean-java (13)
- istack-commons (4)
- apache-directory-server (3)
- polyglot-maven (2)
- mustache-java (2)
- maven-processor-plugin (2)
- ruby-license-finder (0)
- elki (0)
- bridge-method-injector (0)

The maven-bundle-plugin is under work in Debian, a fix is expected
today and will enable further testing of its dependencies.

Other outstanding packages that FTBFS with OpenJDK 9:
- bnd* (33)
- gradle* (16)

Regards,
Tiago
