Ed Merks commented on TIKA-4945:
--------------------------------
Yes, I will try to do whatever is in my capacity to do in order to help verify
any proposed changes.
Note that the 3.3.2 version did not contain an provided or required services:
It only has this:
{color:#000000}Require-Capability
osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=11))"{color}
So this appears to be a new aspect of 4.x...
I need to find a bit of time to look at your source code to see where this
comes form. Likely some BND utilities are generating this during the build,
but I haven't checked.

> When trying to install the following version in an OSGi (Equinox) environment:
> [https://repo.maven.apache.org/maven2/org/apache/tika/tika-core/4.1.0/]
> It fails like this:
> {color:#ff0000} ERROR: org.eclipse.equinox.p2.director code=0 Missing
