Hello,
It has taken me some time (weeks!) but I think I've found the solution to
the problem:
1. Added "org.apache.felix.jaas.boot" to
"org.osgi.framework.bootdelegation".
2. Added
"-Xbootclasspath/a:/opt/sling/artifacts/org/apache/felix/org.apache.felix.jaas/1.0.2/org.apache.felix.jaas-1.0.2.jar"
to the JVM arguments.
And the null context class loader was apparently not the sign of an issue,
from what I read about OSGi, but also as seen in practice:

> [LoginContext]: Discovered ServiceProviders for ClassLoader: null
> java.util.ServiceLoader$ProviderImpl@5a0e195d
> [LoginContext]: org.apache.felix.jaas.boot.ProxyLoginModule loaded via

Why this bit of configuration was not necessary for the full Sling
distribution to work, I have no idea.
If someone knows and can enlighten me, I'd be curious.
