This isn’t really possible. The osgi-compendium package is not just a program
or library; it represents a specification published by a standards body, the
OSGi Alliance. The specification supports the java servlet API 2.5 and above.
We cannot simply update to 3.1 since that could break any consumers using 2.5 —
also the package would not comply with the published specification.
This is the maintainer address of Debian's Java team
debian-j...@lists.debian.org for discussions and questions.
