    Description

      Migrating an application, which uses karaf-assembly, it running into "Candidate permutation failed due to a conflict between imports" when migrating from the Fuse 7.7 to 7.8 BOM.

      Previously, the app migrated from Fuse 7.6 to 7.7 without any issues.

      The startup looks like it just hangs until you turn on debug logging and see:
