[jira] [Commented] (FELIX-6521) Stop exporting org.osgi.service.component packages
[ https://issues.apache.org/jira/browse/FELIX-6521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17626189#comment-17626189 ]
Nicolas Roduit commented on FELIX-6521:
---------------------------------------
Since this change I can't launch the SRC bundle, is there a particular configuration to apply?
In order to reproduce the problem, just download Felix framework 7.0.5 and add 3 bundles (org.osgi.util.function-1.2.0.jar, org.osgi.util.promise-1.2.0.jar, org.apache.felix.scr-2.2.4.jar).
Result:
{code:java}

> Priority: Major

> I would like to stop exporting the org.osgi.service.component packages from the SCR bundle and instead only import them. This is to make the implementation more predictable when installed along side the OSGi specification API bundle with GAV org.osgi:org.osgi.service.component:1.5.0 which only exports and does not import this package. This will reduce the confusion and possible issues with multiple exporters of that package.
