Huh?? I'm certainly not blocking anyone from fixing jasperreports or
libpam4j. I'm just putting the issues into perspective and trying to
convince you that there are more important things to do with our limited
resources. I failed, well, so be it. But please don't see that as
negative, I hold absolutely no grudge against your position, I'm
sincerely grateful that you invest so much time into the Debian Java
ecosystem and the security support. I'm just someone pragmatic that
likes doing things that make sense, and I feel concerned when someone is
about to spend a significant amount of time on something unnecessary
(not by the rules, but by the impact it'll have on actual users).

Do you mean that I'm holding important information and that's why we
don't see more contributors joining the party? I don't think this is a
fair assessment. Look at the Java 9 transition, Chris posted the bug
list months ago and no new contributor showed since, we are just a
handful of regular contributors slowly fixing the bugs. For the Maven 3
transition I requested some help with plexus-utils2 last month and I got

I respectfully disagree. Depending on a Java library provided by the
operating system for someone doing cross-platform Java development is a
bad idea for many reasons :
- The application becomes non portable across operating systems.
- In addition to package formats, the developer has to deal with even
more OS specific details (Debian has version X, Ubuntu has Y, and Fedora
doesn't have it, dealing with that in a standard Maven build is not
- It becomes more difficult to develop on another OS (for example
Windows) and deploy on Debian.
- More differences between platforms means even more QA work.
- For a given OS, it might be necessary to have version specific
packages (i.e. one for Debian 8 and another one for Debian 9). A
corollary is that the same package may not be used for both Debian and
- The application is tied to the version of the library in Debian which
can't be upgraded at will.
- Security support is nice but meaningless, since the developer has to
support other operating systems and upgrade its dependencies everywhere
I can see some notable exceptions though:
- libraries intended to interact with a specific version of an
application in Debian. For example mysql-connector-java which is aligned
with the version of MySQL/MariaDB in Debian.
- libraries with a native part (like JNA or tomcat-native) since Debian
supports more architectures.

Yes but nothing formalized, like a dedicated field at the package level
in debian/control, or another medium detached from the package that
could be queried and displayed to the users.

The upgrade beyond 6.3.1 looks a bit more involved dependency wise. I'll
give it a try.
