While working on the odlparent 4.0.0 bump in ~~NEUTRON-197~~, I've come across a problem I want to record here, so that if other projects use EcliseLink (org.eclipse.persistence) they can benefit from the lesson lernt here, and so that we can see if perhaps a more permanent solution in odlparent is required:

All those JAXB related tests in neutron-spi which all basically just unmarshal JSON were failing this like:

javax.xml.bind.UnmarshalException
 - with linked exception:

Researching this a bit, one finds this kind of stuff:

Indeed if I add this to neutron/neutron-spi/pom.xml as part of c/76089 then those tests pass again:

<dependency>
  <groupId>org.glassfish</groupId>
  <artifactId>javax.json</artifactId>
  <version>1.1.2</version>
  <type>bundle</type>
  <scope>test</scope>
</dependency>

so all good I guess - it's just curious that we would suddenly require this; looks like one of the bumps of things like EclipseLink itself, or javax.json (JSON-P) or Jackson or perhaps even Karaf had this unintended side effect? Perhaps before there was transitive dependency from the the API to this Impl which now needs to be added explicitly.

FYI: Those tests (above) are standalone; I still have to see how it works under OSGi... but hopefully it's possible to get it working there as well (although eclipse-ee4j/jsonp/issues/96 looks a little bit worrying in that regard).

skitt, tpantelis, rovarga this isn't really blocking me in ~~NEUTRON-197~~, with the workaround above (I think), but I thought you may be interested in hearing about this, even if just to keep it at the back of your minds for later.
