OSGi install fails because sun.misc package is not exported via Felix

[dzharikhin]

Hi!, trying to install bundle I get this one
org.osgi.framework.BundleException: Unresolved constraint in bundle io.reactivex.rxjava [274]: Unable to resolve 274.0: missing requirement [274.0] package; (package=sun.misc)
at org.apache.felix.framework.Felix.resolveBundle(Felix.java:3409)
at org.apache.felix.framework.Felix.startBundle(Felix.java:1709)
at org.apache.felix.framework.BundleImpl.start(BundleImpl.java:905)
at org.apache.felix.framework.BundleImpl.start(BundleImpl.java:892)

I see there is fallback implemented in src if Unsafe is unavailable,
but in MANIFEST.MF package sun.misc is still strongly required.
It would be nice to make resolution:=optional for this package because its absence breaks nothing inside

To append packages to the default set of exported system packages add needed value to this propertie:
org.osgi.framework.system.packages.extra=sun.misc

[dzharikhin]

It is wrong way. This package is not public any way. And that package import is really optional - I see there is fallback implemented already)

You can also fix this by adding com.diffplug.osgi:com.diffplug.osgi.extension.sun.misc:0.0.0 from MavenCentral. See here for more details on extension bundles.
