Hi all,

I am trying to upgrade an OSGi based software platform (Wso2 Carbon version 4) to be able to run on java 10. I have upgraded OSGi dependencies to Luna and I was able to build it with java 8. When the framework is launched on java 10 some bundles are not activated due to the missing service org.eclipse.osgi.service.resolver.PlatformAdmin.

osgi> b 98
org.wso2.carbon.core_4.4.3511 [98]
  Id=98, Status=RESOLVED    Data Root=/Users/tharindu/IdeaProjects/luna-carbon-kernel/distribution/product/modules/distribution/target/wso2carbon-4.4.3511/repository/components/default/configuration/org.eclipse.osgi/98/data
  "No registered services."
  No services in use.
gogo: IllegalStateException: Missing service: org.eclipse.osgi.service.resolver.PlatformAdmin
osgi>

Any clue to solve the above issue is highly appreciated.

I don't think Luna will run on Java 10. Why not upgrade to Photon or 2018-09?

I have tried with Photon and I was not able to build it. I have posted about that here: https://www.eclipse.org/forums/index.php/t/1095003/
Next I decided to try with luna because luna maven dependencies were already available in the company maven repo. (Since equinox artifacts are not published in maven central repo we have to download and manually install them in a local/company repo.)
Do you think I should try it with Oxygen?

See https://search.maven.org/search?q=g:org.eclipse.platform%20AND%20a:org.eclipse.osgi&core=gav for the versions published to maven by the Eclipse project.

This particular issue is because with Luna the org.eclipse.osgi.service.resolver.PlatformAdmin service got removed from the framework. You can add it back by including the fragment org.eclipse.osgi.compatibility.state

But to be clear, Oxygen would be the first release to really work on Java 9 or later. And if you are upgrading, you should move up to the very latest.

Thank you very much. Adding that bundle fixed the issue.
Since I have already put some effort on Luna I like to try a little further with it. I will upgrade to a later version if I hit another issue like this one.

Luna release included a significant refactoring of the Equinox framework in order to accommodate changes in the OSGi R6 specification and get rid of some long term technical dept. All releases after Luna I expect to be a pretty straight forward migration to. So the effort to get to Luna should not be a waste since it should help with your migration to the latest release.
