This is getting into "why doesn't my app run if I remove
things it needs to run ?" territory.
A headless environment does not mean that fonts aren't needed.
Headless environments are used to do text rendering.
So whilst we could have a discussion about what form the error
should take, at some point you should get an error.
Silently returning from all text rendering related API calls without
failing would be even worse.
If you don't want to do anything with rendering, why is any kind
of toolkit (headless or otherwise) being loaded ?
The native fontconfig library isn't a runtime linker dependency only
because we started using it before it could be guaranteed available
for all the distro versions we support.
If we were doing this today we'd almost certainly link at compile time
and then if you did not install it your binary would not even start -
even in
headless mode.
I say this not because it would somehow improve your situation, but
to make clear that libfontconfig is not an optional library.
So on Linux fonts need to be provided by at least one of :
- the system + located using libfontconfig
- in the JRE lib/fonts folder
- in one of several unspecified system locations that are still
searched by the code
that pre-dates libfontconfig
The 2nd + 3rd of these should be considered legacy.
The 2nd applied to Oracle JDK when we shipped fonts, but adding your own
fonts there is no longer supported by Oracle JDK or OpenJDK.
The only scenario I can think of that might get by is where the app
is supplying fonts using Font.createFont() and *only* those are used /
needed
I suspect that is a rare case and would help only a very specific
controlled application
where you knew you used those fonts and no other fonts.
