---------------------------------------
Note that with Java 11, Sling components do not seem to load anymore:

> When running on Java 9 post SLING-7186 startup fails due to the {{javax.annotation}} package no longer being exported by default, e.g.
> {noformat}org.osgi.framework.BundleException: Unable to resolve org.apache.sling.installer.core [2](R 2.0): missing requirement [org.apache.sling.installer.core [2](R 2.0)] osgi.wiring.package; (osgi.wiring.package=javax.annotation) Unresolved requirements: [[org.apache.sling.installer.core [2](R 2.0)] osgi.wiring.package; (osgi.wiring.package=javax.annotation)]

> The interesting part here is that the {{javax.annotation}} classes that are required - for instance {{javax.annotation.CheckForNull}} are _not_ part of the JDK-provided {{javax.annotation}} package, they must come from another jar. In fact, we don't have that Jar deployed in the starter, but instead the JDK provides:
> {noformat}
> Generated.class
> PostConstruct.class
> PreDestroy.class
> Resource.class
> Resources.class
> {noformat}
> In a sense, this is very close to the root cause of SLING-7135 - solving one might solve both but the symptoms are very different so raising it separately.
