Gert Vanthienen commented on FELIX-1914:
----------------------------------------
Add a *{{dev:dynamic-import}}* to enable/disable dynamic imports on a bundle in
http://svn.apache.org/viewvc?view=revision&revision=887748
When disabling the bundle, the command will determine what packages have been
added.
Example:
{noformat}
ka...@root> osgi:update 32

>
> At development time, people sometimes bump into classloading or bundle
> resolution issues. Proposing to add a subshell with a few development tools
> that can be used to troubleshoot these issues:
> - To solve the "unable to resolve due to constraint violation", we could
> build a tool that discovers multiple bundles exporting the same package that
> are needed to resolve the given bundle to give people a clue which
> uses-constraints might be involved
> - To solve a CNFE, we could build a tool that takes a snapshot of imports,
> enabled dynamic imports and refreshes the bundle and then checks the imported
> packages again to see which imports were added by the dynamic import
