I'd be content with having a regression test, although I'm not sure how
involved it would get. This time the Import-Package value was
syntactically incorrect, this might get caught by static analysis. Last
time I stripped an Import-Package (the one for XZ when I added the
Brotli dependency IIRC), so the manifest was valid but you have been
unable to use the algorithms provided by XZ. This is a runtime issue
that really requires a test, I guess.

At least not when I use it the naive way (this is based on the rel/1.16

with -X I only get a Maven internal stack trace. Same for the 3.4.0
version that is requested by commons-parent 43.

TBH I don't want to dig deeper here as I really think we need runtime
verification over static analysis.
