This pax exam test, using the karaf runner, with karaf 4.2.5, runs with openjdk-8 but fails with openjdk-11:
https://github.com/steinarb/scratch/blob/authservice/use-java-11/authservice.tests/src/test/java/no/priv/bang/authservice/tests/AuthserviceIntegrationTest.java#L25

Will pax exam work with openjdk-11? Should switching JDK have worked
out of the box? Or will the test code or dependencies need to be
modified?

Here's the error message from the failing build:

Hi,

You need to add some VMOption by yourself, something like

new VMOption("--add-reads=java.xml=java.logging"),
                new VMOption("--add-exports=java.base/org.apache.karaf.specs.locator=java.xml,ALL-UNNAMED"),
                new VMOption("--patch-module"),
                new VMOption("java.base=lib/endorsed/org.apache.karaf.specs.locator-"
                    + System.getProperty("karaf.version") + ".jar"),
                new VMOption("--patch-module"), new VMOption("java.xml=lib/endorsed/org.apache.karaf.specs.java.xml-"
                    + System.getProperty("karaf.version") + ".jar"),
                new VMOption("--add-opens"),
                new VMOption("java.base/java.security=ALL-UNNAMED"),
                new VMOption("--add-opens"),
                new VMOption("java.base/java.net=ALL-UNNAMED"),
                new VMOption("--add-opens"),
                new VMOption("java.base/java.lang=ALL-UNNAMED"),
                new VMOption("--add-opens"),
                new VMOption("java.base/java.util=ALL-UNNAMED"),
                new VMOption("--add-opens"),
                new VMOption("java.naming/javax.naming.spi=ALL-UNNAMED"),
                new VMOption("--add-opens"),
                new VMOption("java.rmi/sun.rmi.transport.tcp=ALL-UNNAMED"),
                new VMOption("--add-exports=java.base/sun.net.www.protocol.http=ALL-UNNAMED"),
                new VMOption("--add-exports=java.base/sun.net.www.protocol.https=ALL-UNNAMED"),
                new VMOption("--add-exports=java.base/sun.net.www.protocol.jar=ALL-UNNAMED"),
                new VMOption("--add-exports=jdk.naming.rmi/com.sun.jndi.url.rmi=ALL-UNNAMED"),
                new VMOption("-classpath"),
                new VMOption("lib/jdk9plus/*" + File.pathSeparator + "lib/boot/*”)

You can take a look at [1] to get more details about how we do it in Karaf.

I'll give it a look and report back how it worked out. Thanks!

(the pax exam tests were the last thing keeping me on openjdk-11,
everything else seems to be working, up to and including running my
applications in karaf. Debian has dropped openjdk-8 from their current
testing, meaning it will be gone from the next stable, and this
energized me into finally making the transition to "new-style Java")

I've added the VMOptions to the startup but I still get the same stack
trace, ie. a NullPointerException thrown from here:
public class FrameworkExtensionInstaller {
...
void addExtensionContent0(Collection<ModuleRevision> revisions, Module systemModule) throws BundleException {
if (CL == null || ADD_FWK_URL_METHOD == null) {
// use the first revision as the blame
ModuleRevision revision = revisions.isEmpty() ? null : revisions.iterator().next();
==> throw new BundleException("Cannot support framework extension bundles without a public addURL(URL) method on the framework class loader: " + revision.getBundle()); //$NON-NLS-1$
}

The exception happens in the throw, and the only thing I can see causing
the NPE, is that revisions isn't empty, but contains at least one null
element.

The stack trace, is:

Er no... the collection revision is empty so revision becomes null and
fails in revision.getBundle() in the throw.

I made the following JIRA for the problem:

And the reason it tries to throw an exception tin the first place, is
that ADD_FWK_URL_METHOD is because the "addUrl" method is missing from
the URL class.

From the google searches I've made addUrl() hasn't appeared on the list
of removed stuff in java >= 9.

And it looks like there was no URL.addUrl() method in the URL class of
java-8:

Not sure if this is a karaf bug or a pax exam bug, but it is a bug when
running under java 11.

The method the code setting up ADD_FWK_URL_METHOD is looking for, isn't
a method on URL.

The code looks for, and doesn't find, the method
sun.misc.Launcher.AppClassLoader#addUrl(java.net.URL)

So I googled for AppClassLoader and java 11 and found this:
https://blog.codefx.org/java/java-11-migration-guide/#symptoms-2

With Java-11 AppClassLoader no longer is a URLClassLoader, and therefore
(presumably) no longer has an addUrl() method and that's why the pax
exam boot of OSGi fails.

Hi Steinar,

Good catch, and this is a known issue in 

And this issue has already been fixed.

To run your test with JDK11+eclipse, I think you should use

<dependency>
                <groupId>org.eclipse.tycho</groupId>
                <artifactId>org.eclipse.osgi</artifactId>
                <version>3.13.0.v20180226-1711</version>
            </dependency>
Which contains the fix.

No luck, unfortunately.

I get a different stack trace, but it still fails:

Hi,

If you can send a reproducer project which I can build and run to reproduce this problem, I will take a close look.

Cheers

git clone https://github.com/steinarb/authservice.git
cd authservice
git checkout work/use-java-11
mvn clean install

If your Java is java-11, then the maven build will fail in the
authservice.tests project, that contains the pax exam test.

Thanks!

Side note: I did not intentionally use the eclipse OSGi framework for
the pax exam test.

I pulled in the pax-exam-container-karaf which does not pull in an OSGi
framework, and then needed to make a reference to the pax jdbc karaf
feature, which *does* have a (unintentional?) maven transitive
dependency to the eclipse OSGi framework, and then things started
working, and I didn't investigate anymore.

So I tried using the same osgi framework I'm using for regular karaf
usage

I noticed that the osgi.core version 6.0.0 artifact I have been using, was pretty old (July 2014):
https://mvnrepository.com/artifact/org.osgi/org.osgi.core

So I looked for OSGi 7 and found this:
https://mvnrepository.com/artifact/org.osgi/osgi.core

The version 6.0.0 osgi.core artifact is from January 2015.
The version 7.0.0 osgi.core artifact is from April 2018.

I've tried with both of them, but got the same stack trace (or very
similar stack trace) as the org.osgi.core 6.0.0 framework (the one below
is from osgi.core 7.0.0):

So this Java-11 change is possibly something that affects all OSGi frameworks...?

I've googled a bit more and found this in the release notes of the
recently (May 2019) released felix framework 6.0.3:
* [FELIX-5720] - Use PlatformClassLoader as boot classloader on java9

https://svn.apache.org/repos/asf/felix/releases/org.apache.felix.framework-6.0.3/doc/changelog.txt
https://mvnrepository.com/artifact/org.apache.felix/org.apache.felix.framework/6.0.3

The Pax Exam test still failed, but the stack trace is different (no
mention of the URLClassLoader):

Thanks! No luck on my side, unfortunately...:-(

It still fails with the error messages below (However, I had to apply
everything except the top pom manually, and I may have done something
wrong...?
https://github.com/steinarb/scratch/commit/0e3f91871eadff73414879a165e3675a43143088)

I tried bumping felix framework to 6.0.3 but I still got the error

karaf feature org.ops4j.pax.jdbc:pax-jdbc-features:xml:features:1.3.1
pulled in both eclipse equinox and the felix OSGi framework:

So I suppressed both OSGi frameworks from the pax-jdbc-features
dependency and tried first a new eclipse equinox version and then felix
framework 6.0.3.

Both gave me errors on framework initialization but the errors were
different.

When using eclipse equinox 3.13.0.v20180226-1711 I got the following
stack trace (looks like it's getting the OSGi type definitions from a
different bundle...?):

You can't use Felix framework 6 as it's OSGi R7.

I will take a look on your branch. I can confirm that karaf itests, including pax jdbc work in itest.

I switched to 5.6.12 which is the one that karaf master currently uses,
but got the same failure as with 6.0.3 ("Error installing bundle listed
in startup.properties...").

Stack trace included below.

Thanks!

I've tried building karaf (both the master branch and the jdk12 branch)
on my development system, and I get test errors, so it could be
something with my setup...?

My setup:
debian 9.9 "stretch" (ie. current stable), amd64
openjdk-11:amd64 11.0.3+1-1~bpo9+2 (installed with apt-get)
maven 3.6.0 (installed from tar-ball)

Did you try with a clean maven repo ?

It's certainly an environment issue as both Jenkins at Apache and my machine are ok.

By the way, both machines use jdk 11.0.3 (Oracle).

Could you share some details about your build environments? OS? maven
version? Java version?

> By the way, both machines use jdk 11.0.3 (Oracle).

Hm... that could be the difference.

But I would still like to get things working with openjdk.

That's very similar to my setup:
1. same maven version (3.6.0)
2. slightly older (I think) openjdk-11 than what I have:
sb@lorenzo:~$ java -version
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Debian-1bpo92)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Debian-1bpo92, mixed mode, sharing)
3. same processor architecture
4. different os, but both are unix'is systems, and file and socket
operations and semantics should be similare, virtual management
semantics should be similar, so I doubt that make any difference

Hm... I basically have no idea what's missing in my setup...:-)

You run into this error when building latest karaf master branch with JDK11?
