      Description

      I have very simple OSGI bundle, which uses just camel-core.

      When I run it, an exception is thrown:

      Camel-core bundle should Import sun.misc package

       

      Until this bug is resolved, a workaround is to add "-runproperties: org.osgi.framework.bootdelegation="sun.misc"" to bnd.bnd file
