Bug description

Sometimes, there is a NullPointerException at mb.statix.spec.ApplyRelaxed.apply(ApplyRelaxed.java:35) when running the Statix solver.

Versions

Spoofax version: Spoofax 3 development versions
Statix setup: multi-file

Steps to reproduce the behavior

Unfortunately, this only happens sometimes, I have not been able to reproduce it deterministically. I've seen it happen on the buildfarm on pie.lang and on my laptop on sdf3 in Spoofax 3.

Observed behavior

NullPointerException is thrown.

Expected behavior

No exceptions are thrown.

Additional context

Stack trace from the buildfarm:

I was trying to reproduce this, but unfortunately the Spoofax 3 build failed. See Slack for details. Can you comment when that is resolved? Then I'll try to reproduce and fix it.
