Addresses issue raised in this discussion thread #3089. Thanks @schaefa for reporting!

From https://github.com/diffplug/osgiX

The cause of the problem is that OSGi doesn't supply the entire JRE to its bundles - it only provides the most standardized packages. This means that non-standard packages like sun.misc and sun.reflect aren't available to your bundles, even though they are in common usage.

graphql-java does not directly use anything from sun.misc, but it still is turning up in the MANIFEST.MF file generated by the plugin biz.aQute.bnd.builder.

This PR removes sun.misc.* from the Import-Package header.
