Dave, is it possible
that Greg didn't copy the three plugins to a local directory and instead
tried to reference them directly from the server?

Greg, with Dave's
approach, will you need to package those plugins with PTP?

I'm not sure what's different. I have a Java 12 runtime. I downloaded the
java-activation-1.2.0,jar, jaxb-api-2.4.0-b-180830.0359.jar and jaxb-osgi-180830.0438.jar
from the maven repository files into a local directory, added that directory
as a local repoistory in the photon.target file, and changed the import
for com.sun.xml.bin in the org.eclipse.ptp.rm.jaxb.core MANIFEST.MF file
to com.sun.xml.bind.v2. Then I reloaded the target definition file and
started a PTP runtime instance. 
I was able to open the run configuration dialog, pick any target system
configuration and pick a remote connection name. Then the resources page
would fill in properly.

If I backed out those changes and ran again using the Java 12 runtime,
I got the error for the missing class.

Hi Dave,

Yes, I’ve spent the better part of a week on it and I’m still no closer…
I’ve tried everything, including creating a fragment with the dependencies
but I’m still getting the error.

Looking at this further, it seems that CDT has solved this or a similar
problem
https://www.eclipse.org/lists/cdt-dev/msg33366.html
https://bugs.eclipse.org/bugs/show_bug.cgi?id=542644

I also found this, which suggests using com.sun.xml.bind:jaxb-osgi to get
the missing JAXB code, where I found https://mvnrepository.com/artifact/com.sun.xml.bind/jaxb-osgithat seems to point to the location to get it from.
I don't know if this helps or is even possible to use in an eclipse.org-hosted
project

I'm looking at this problem since it affects my plugin once Java 8 is no
longer supported. I'm not sure I'm anywhere near on the right track to
figure this out. I found quite a few references to this problem within
the past year by Google search using the words ContextFactory and Eclipse,
a number of which refer to PTP bug 541264

My understanding of the solutions suggested are to use versions 2.2.0 of
the com.sun.xml.bind and javax.xml.bind, which I think means I need to
find repositories that have these versions of the packages.

I tried updating the photon.target target definition file to use a later
Orbit repository, I20190320195810 which seems to have these, but that did
not help. I also found https://www.jesperdj.com/2018/09/30/jaxb-on-java-9-10-11-and-beyond/which explains how to specify a dependency for a maven build, but I'm not
sure where this gets specified.

Am I anywhere near the right track to figure this out?
