[jira] [Commented] (KARAF-7768) Remove karaf.specs

["Robert Varga (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KARAF-7768?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17946872#comment-17946872 ] 

Robert Varga commented on KARAF-7768:
-------------------------------------

So, as far as I am reading this right, specification-wise, we should be bridging to either
# SPI-Fly as [a consumer|https://aries.apache.org/documentation/modules/spi-fly.html#_consumers], or
# XML Parser Service as [specified as OSGi Companion R8|https://docs.osgi.org/specification/osgi.cmpn/8.0.0/util.xml.html]

The former boils down to a Require-Capability header, which can be added via [the wrap: protocol|https://ops4j1.jira.com/wiki/spaces/paxurl/pages/3833898/Wrap+Protocol].
The latter has a well-known API which user can exploit and we should provide, probably as part the framework feature, perhaps bridging to a reasonably-configured platform provider.

Also note that features.core implies Jackson, which implies woodstox, which implies stax2-api: our JSON library brings into the picture a StAX implementation which has its own [OSGi injection mechanism|https://www.javadoc.io/static/org.codehaus.woodstox/stax2-api/4.2.2/org/codehaus/stax2/osgi/package-summary.html]. We need to decide how this dependency is integrated: we can say all Karaf installations are using WoodStox for XML parsing, but is that a reasonable thing to do?

> As noted in https://lists.apache.org/thread/dhfzyyph43h9hqn9fd47qwh1krvx83tl, it seems we can remove our patching of javax.xml(.ws) by including SPI Fly directly in the system.
> Prototype whether this idea works and implement it if it does.
