Installation failure when updating bundles with required bundles
----------------------------------------------------------------
Key: FELIX-701
URL: https://issues.apache.org/jira/browse/FELIX-701
Project: Felix
Issue Type: Bug
Components: Bundle Repository (OBR)
Reporter: Felix Meschberger
Consider a system with two bundles installed:
Bundle A, Version 1, imports package B.x with version 1, started
Bundle B, Version 1, exports package B.x with version 1, started
Now, Bundle A should be updated to version 2:
Bundle A, Version 2, imports package B.x with version 2
This causes OBR to select version 2 of Bundle B to satisfy the requirement of
version 2 of Bundle A.
Bundle B, Version 2, exports package B.x with version 2
Now, the ResolverImpl will try to update Bundle A with the new version, which
fails because Bundle A is automatically started again by the framework but does
not resolve due to the version mismatch on the package import. This throws an
exception causing the ResolverImpl to abort the deployment.
A simple fix to this problem is, that the ResolverImpl temporarily stops Bundle
A before updating it and starting Bundle A again after the update. This allows
the resolver to continue with the deployment of the required bundle and finally
starting everything again.
