Re: [ptp-dev] PTP java.lang.ClassNotFoundException: for com.sun.xml.internal.bind.v2.ContextFactory

Greg
I issued a pull in my workspace to get the updated code. Then I ran using Java 8 and the run configuration dialog worked correctly. I then switch to Java 12, first as a Java 11 execution environment and then as a Java 12 JRE. In both cases I got the exception for the missing ContextFactory class.

Then I downloaded the parallel package. That worked with Java 8 which is the default Java. I added a -vm parameter to eclipse.ini to specify the path to the Java 12 javaw executable and the run configuration dialog worked correctly. I did verify that I had the right format for the eclipse.ini by using an invalid path to javaw, so I'm sure I was running with Java 12.

I guess something is wrong with my workspace, but since it works in the parallel package, I guess that's proof this is fixed.

Thanks for fixing this.

Dave

Hi Dave,

There should be a new build you can try now. This should work for both Java 8 and Java 11. If you like, you can also try the Parallel Package from here: https://ci.eclipse.org/packaging/job/simrel.epp-tycho-build/451/artifact/org.eclipse.epp.packages/archive/

      Dave,

      My goal was trying to get it to work on Java 11/12. I thought it might be broken on Java 8. I’m going to try to use a fragment to handle Java 11 so Java 8 should not be affected. I’ll let you know when it’s ready to test.

      Regarding the version of Java used to build PTP. I believe it shouldn’t matter as each plugin includes a Bundle-RequiredExecutionEnvironment that specifies the minimum Java version required to execute the plugin. The build process is supposed to adhere to this requirement so that API changes do not cause problems. In any case, it will be built with Java 8 by the Eclipse CI server.

          I did not rebuild PTP when switching between Java 8 and Java 12. I just switch Java JRE and run environment in the run configuration dialog that starts the PTP runtime instance.

          Anyway, as far as I know I am building PTP only with Java 8 since that is the only Java in my Windows PATH. I downloaded the Java 12 code as a zip file and manually unpacked it to keep anything in the Java install process from changing my environment. So I think the only thing my Eclipse IDE knows about my Java 12 installation is that it is an additional JRE (set as the default in the Installed JRE in the IDE preferences)

          If PTP was built for Java 11/12, I doubt it will run smoothly on Java8, as interfaces may have changed. We know the other way around is not true, although that shouldn't be the case.

          Also, is it possible to check the Java RTE version at runtime and do things differently for each version?

          Or maybe we can do that with some magic and use different PTP plugin versions in hpctView, depending on the Java RTE version?!?

          One thing is for sure, PTP needs to support Java >=11. What do other plugins that use JAXB do?

          The original problem with a missing ContextFactory class when running with a Java 12 JRE seems to be fixed. I can open a run configuration dialog, select a target system configuration and a remote connection and have the resources tab fill in proiperly.
          I noticed this warning when I created a synchronized project. I'm not sure if it means anything or not, and don't know if this is due to something in PTP code. I created a second synchronized project using a Java 8 runtime and did not see this. When I created a third synchronized project while running as a Java 12 JRE I did not see this warning.

          I tried running with a Java 8 JRE and and ran into problems when trying to open the run configuration dialog.

          First, I get this popup when I start the runtime instance
          <17599189.gif>

          When I opened the profile configuration dialog, I got this popup, but then the dialog opens
          <17183327.gif>
          If I try to select a connection I get the same popup and can't select a connection.

          The runtime instance starts and the run configuration dialog resources tab fills in properly when I select a connection name. I don't have either OpenMPI or MPICH on my test system so I specified the application as /bin/ls and clicked run. That generated output to the console and I didn't see any further errors logged.

          If I change the MANIFEST.MF file in org.eclipse.ptp.rm.jaxb.core and use the Java 8 runtime I get the same behavior including the popup and exception.

          Unfortunately this is the problem. Projects hosted on Eclipse can’t be built using arbitrary components from a maven repository. Everything has to be obtained from Eclipse repositories, and from what I’ve been able to determine, the latest jaxb version is 2.2.0 which doesn’t seem to work. I’ve been looking at using Eclipselink but haven’t been able to get that to work either.

          Also, it would be worth checking that Dave’s solution works for Java 8 as well as Java 11/12. Whatever the solution is, it also needs to work with both versions.

          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.

          Looking at this further, it seems that CDT has solved this or a similar problem

          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?
