Polling News Feed Has Encountered a Problem

Comment 1 Giambattista Bloisi Friend 2018-09-28 12:24:05 EDT

I noticed the same problem when switching from Java 10 to Java 11. I think it is caused by the removal of jaxb package from java 11 (see http://openjdk.java.net/jeps/320), but I did not find a way to add the jaxb-ri jars (https://github.com/javaee/jaxb-v2) to the eclipse classpath by editing the eclipse.ini file. I think this requires some internal fix.

Comment 2 James Bryant Friend 2018-10-01 16:53:05 EDT

I can report the same problem with Photon, JDK 11, and Windows 10.

Comment 3 Kondal Kolipaka Friend 2018-10-02 05:48:29 EDT

Having the same problem with the below eclipse 4.9.0 build. Version: 2018-09 (4.9.0) Build id: 20180917-1800   Here is the error: ------------------- java.lang.NoClassDefFoundError: javax/xml/bind/JAXBContext 	at org.eclipse.mylyn.internal.commons.notifications.feed.FeedReader.parse(FeedReader.java:52) 	at org.eclipse.recommenders.news.impl.poll.DefaultFeedItemStore.parseNewsItems(DefaultFeedItemStore.java:135) 	at org.eclipse.recommenders.news.impl.poll.DefaultFeedItemStore.udpate(DefaultFeedItemStore.java:53) 	at org.eclipse.recommenders.news.impl.poll.DefaultNewsPollingService.fallbackToLocalStore(DefaultNewsPollingService.java:136) 	at org.eclipse.recommenders.news.impl.poll.DefaultNewsPollingService.poll(DefaultNewsPollingService.java:104) 	at org.eclipse.recommenders.news.impl.poll.DefaultNewsPollingService.poll(DefaultNewsPollingService.java:64) 	at org.eclipse.recommenders.internal.news.rcp.poll.PollFeedsJob.run(PollFeedsJob.java:70) 	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

Comment 4 Kondal Kolipaka Friend 2018-10-02 05:56:21 EDT

Seems to be this is caused by   org.osgi.framework.BundleException: Could not resolve module: org.eclipse.mylyn.commons.xmlrpc [309]   Unresolved requirement: Require-Bundle: org.apache.xmlrpc; bundle-version="[3.0.0,4.0.0)"     -> Bundle-SymbolicName: org.apache.xmlrpc; bundle-version="3.0.0.v20100427-1100"        org.apache.xmlrpc [72]          Unresolved requirement: Import-Package: javax.xml.bind

Comment 8 Thad Humphries Friend 2018-10-15 11:07:15 EDT

Sorry, but adding adding java.xml.bind through Eclipse Orbit is not resolving this issue for me. I've tried adding the Orbit URL to my download sites and installing "XML Binding for Java" on two macOS Mojave machines, both with Eclipse Photon. Launching Eclipse with Java 11 still shows the polling news error message:  "An internal error occurred during: "Polling news feeds".      javax/xml/bind/JAXBContext"  although the JAR (when I download and look at it) contains javax/xml/bind/JAXBContext.class.  It seems the only thing to do is to turn off automatic news polling in Preferences.

Comment 9 Dennis Gesker Friend 2018-10-24 14:34:33 EDT

Having the same issue with JDK 11 on KUbuntu 18.10 using Version: 2018-09 (4.9.0) Build id: 20180917-1800

Comment 10 Claude Nobs Friend 2018-10-25 14:49:39 EDT

Having the same issue with JDK 11.0.1 on Windows 7 using Version: 2018-09 (4.9.0) Build id: 20180917-1800  However deactivating news polling solves the error popup issue for me. (Preferences > General > News)

Comment 11 Sumit Pawar Friend 2018-11-02 14:21:21 EDT

I am facing the same issue on MacOS when installing the plugin for Scala  Error faced : An internal error occurred during: "Polling news feeds". javax/xml/bind/JAXBContext  Is there any solution yet for this problem ?  Regards, Sumit Pawar

Comment 12 Brandon Ho Friend 2018-11-13 20:30:39 EST

I download the latest version below and getting the same error.  Does anyone have a solution?  Version: 2018-09 (4.9.0) Build id: 20180917-1800

Comment 13 Gunnar Wagenknecht Friend 2018-11-19 13:36:31 EST

Is there any plan to fix this going forward for 2018-12?

Gunnar,  I just did a clean install on a Windows 10 system, encountered this problem, and tried your workaround.  It did not work for me.

Yes. Ubuntu 18.04. I just upgraded eclipse to 2018-12 and jdk-11. Is there any way to turn the polling off because this is making eclipse unusable.

Comment 20 Gunnar Wagenknecht Friend 2018-12-19 16:17:30 EST

Thanks for trying the workaround. Is it still the same exception or a different stack trace?  I might have missed one bundle, though. Can you also try and install "Java Architecture for XML Binding (JAXB) Implementation" (com.sun.xml.bind) in addition to "XML Binding for Java" (javax.xml.bind)?

Thanks for your patience trying to investigate workarounds.  FWIW, according to the following email, there might be two more bundles necessary. https://www.eclipse.org/lists/cross-project-issues-dev/msg16288.html  Thus, the complete list of bundles to install should be: - javax.xml.bind 2.2.0 - com.sun.xml.bind 2.2.0 - javax.activation 1.1.0 - javax.xml 1.3.4   I'll try to reproduce the issue and report back.

Comment 26 Dani Megert Friend 2018-12-21 09:28:45 EST

At this point the simplest advice for users is to use Java 8. Note, that even if using Java 8 to run the Eclipse IDE, you can still use Java 11 in your projects.

Comment 27 Thad Humphries Friend 2018-12-21 09:36:06 EST

Use Java 8? Really?!   When I set -vm to /Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home in /Users/thad/Applications/java-2018-09/Eclipse.app/Contents/Eclipse/eclipse.ini, Eclipse would not start. IIRC the error was that it couldn't find main in org.eclipse.equinox.launcher_1.5.100.v20180827-1352.jar. So I switched back to Java 11 and turned off News notices (which I've never read in 12+ years anyway).

(In reply to Thad Humphries from comment #27)            > Use Java 8? Really?!                        Yes, really. I can't comment on your problem but Java 8 is a supported runtime for 4.10. If it does not work for you, then please file a bug report.

Sandro,  I was speculating. Maybe it's possible to set something in the eclipse.ini file to fix this, but I've not tried. We have switched to Amazon Corretto's OpenJDK 8, and are not moving to Java 11. In any case the news feed feature is of no importance to me, so I don't mind turning it off.

Comment 32 Jason Reed Friend 2019-05-02 15:04:25 EDT

Hello everyone,  Just came across this issue while switching from Java 8 to Java 11 on my system. For those who keep asking about it there is a way to turn off the news polling at least while the Eclipse team get the packages organized again.  Window --> Preferences --> General --> News  Uncheck the "Enable automatic news polling".

Comment 33 Devangee Choksi Friend 2019-06-06 00:25:55 EDT

I have installed Java 12, a window with the following error message is displayed on regular basis:  "An internal error occurred during: "Polling news feeds".  javax/xml/bind/JAXBContext   Please find attached screenshot.  http://prntscr.com/ny7n2e

Project has been archived so nothing will happen.

Comment 36 Jason Reed Friend 2019-09-25 10:50:58 EDT

So does this mean the project will be removed from the next release of Eclipse? I mean not doing anything is not really resolving the problem, it will continue to plauge users every time we set up a new workspace.

Comment 38 Jason Reed Friend 2019-09-25 13:22:14 EDT

Just upgraded to 2019-09 (YAY) and checked in the preferences and the News preferences are still available. So I reactivated them and sure enough I got the error again. So apparently it still needs removed.

My guess it that it wouldn't remove the news plugin if it's already there.
