> 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)]
> 	at org.apache.felix.framework.Felix.resolveBundleRevision(Felix.java:4149)
> 	at org.apache.felix.framework.Felix.startBundle(Felix.java:2119)
> 	at org.apache.felix.framework.Felix.setActiveStartLevel(Felix.java:1373)
> 	at org.apache.felix.framework.FrameworkStartLevelImpl.run(FrameworkStartLevelImpl.java:308)
> 	at java.base/java.lang.Thread.run(Thread.java:844){noformat}
> 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.
