Tim Allison commented on TIKA-4945:
-----------------------------------
Awesome, thank you for giving this a spin. If you have a chance, can you
confirm that [https://ci-builds.apache.org/job/Tika/job/tika-main-jdk17/1696]
works? That includes the last(?) of the osgi PRs.
The big change is that we moved tika-parser-standard dependencies from optional
to required so there will be fewer surprises at runtime.
Again, we have nearly no OSGi expertise among our active devs. We need all the
help we can get. Thank you, again!
