------------------------------------------
Summary: Allow to exclude system packages without redefining all
exports
Key: FELIX-5091
URL: https://issues.apache.org/jira/browse/FELIX-5091
Project: Felix
Issue Type: Improvement
Components: Framework
Affects Versions: framework-5.4.0
Reporter: Christian Schneider
Fix For: framework-5.6.0
There are several cases where the OSGi framework exports system packages by
default but the result is not usable.
For example javax.transaction is exported but the package is not complete. So a
regular case is to exclude this package and provide it as a bundle.
Currently this can be done by redefining org.osgi.framework.system.packages.
The problem is that you then need to redefine all the system packages which is
a big list and additionally differs between java versions.
So I propose to allow to exclude single packages without having to redefine
them all.
One simple solution would be to use org.osgi.framework.system.packages.extra
and allow to specify a package to exclude by prefixing it with "-".
E.g.
org.osgi.framework.system.packages.extra=-javax.transaction,-javax.transaction.xa
This would avoid creating another framework property.
Alternatively we could introduce a new property like:
org.osgi.framework.system.packages.exclude=javax.transaction,javax.transaction.xa
This property would then only allow to exclude exports.
