Description

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
