[jira] Created: (FELIX-2572) JRE system packages should include
"uses" constraints
JRE system packages should include "uses" constraints
-----------------------------------------------------
Key: FELIX-2572
URL: https://issues.apache.org/jira/browse/FELIX-2572
Project: Felix
Issue Type: Improvement
Components: Framework
Affects Versions: framework-3.0.2
Reporter: Richard S. Hall
Priority: Minor
Fix For: framework-3.2.0
The framework is configured by default to export all JRE packages. Currently, this doesn't include "uses" constraints, which can lead to resolutions that result in execution-time issues (e.g., LinkageErrors) that are hard to diagnose. If we include "uses" constraints on the system packages, then we can avoid this. We should be able to use BND to generate this information.

-----------------------------------
Attachment: jre-package-mac.txt
Updated metadata example, since the original was missing some security-related packages.

-----------------------------------------------------------------
I've taken the attached example JRE metadata and used it to create the system bundle exports. The resulting framework still passed the OSGi CT, our internal tests, and the GlassFish test suite. So, it definitely seems like we could do this, we just have to decide if we should.
It could definitely help in situations where bundles are trying to provide alternative versions of JRE supplied packages. This situation currently causes lots of issues since to the resolver system bundle packages look completely unconstrained since they lack all "uses" constraints.
I am leaning in favor of adding this metadata. Thoughts?
