Subsystem support

[de...@mobigov.com]

 

Subsystems seem very much like features to me and from Alexandre's email
they are almost capable in Karaf. Is there going to be any kind of
official subsystems support in Karaf. Examples would be having features
depend on subsystems or treating subsystems as features. This would give
the capability to have features built using the bnd file similar to what
Benson was looking for in a previous email.

>> NPE in ResolverImpl ------------------- Key: FELIX-5015 URL: https://issues.apache.org/jira/browse/FELIX-5015 [1] Project: Felix Issue Type: Bug Components: Resolver Affects Versions: resolver-1.6.0 Reporter: Alexandre Roman Assignee: David Bosschaert Fix For: resolver-1.8.0 Attachments: FELIX-5015.patch.gz The method getPackageSources in ResolverImpl.java returns a Set. This collection is used in mergeUses (line 1039) in a foreach loop. A null value may be returned by getPackageSources, as a result of querying a Map. In this case, the foreach loop in mergeUses will trigger a NPE. The method getPackageSources should return an empty Set when there is no result.
