I'm the Debian package maintainer for jhove, which is an image validator and really useful for libraries and other cultural heritage institutions.
It is about to get kicked out due to bug #895761. The right thing to do is update the jhove to the current upstream version. However, I haven't touched Java packaging for a very long time, and since then the world has changed. My first attempt went nowhere. Is someone willing to help out? I'm appreciative of assistance at any level: advice, patches, NMU, package adoption. Thank you in advance.
