Stefan Seifert resolved JOHNZON-107.
------------------------------------
Resolution: Won't Fix
setting this to "won't fix" - it is superseded by JOHNZON-108 following the
discussion in GERONIMO-6560.
> Add 'SPI-Provider' bundle header to johnzon-core
> ------------------------------------------------
>
> Key: JOHNZON-107
> URL: https://issues.apache.org/jira/browse/JOHNZON-107
> Project: Johnzon
> Issue Type: Improvement
> Affects Versions: 1.0.0
> Reporter: Stefan Seifert
>
> Johnzon 1.0.0 together with
> {{org.apache.geronimo.specs:geronimo-json_1.0_spec:1.0-alpha-1}} currently
> does not work within OSGi envrionments - the service loader does not found
> the implementation class (see GERONIMO-6560).
> getting service loaders right in OSGi is a bit tricky. there are solutions to
> support this e.g.:
> * https://github.com/apache/geronimo-specs/tree/trunk/geronimo-osgi-support
> * http://aries.apache.org/modules/spi-fly.html
> both need an "opt-in" that means provider bundles like johnzon-core have to
> add special instructions in their manifest to notice the environment it
> provides some service loader implementations.
> since OSGi R5 there is a spec compliant way to do this (covered in the [OSGi
> Enterprise Specification|http://www.osgi.org/Download/Release5] version 5
> chapter 133), but this is currently only supported by the aries spyfly
> implementation, not by the geronimo spec implementation.
> thus my proposal is to simply add a header
> {noformat}
> SPI-Provider: *
> {noformat}
> to johnzon-core - this is supporty by both aries spyfly as the geronimo spec
> implementation.
