Bundle-RequiredExecutionEnvironment: JavaSE-11 for Jetty 10.0.x

[joakime]

Should we upgrade our OSGi manifests to be

Bundle-RequiredExecutionEnvironment: JavaSE-11

Now that Jetty 10.x will be Java 11+ minimum JVM requirement?

Eclipse Equinox added support for JavaSE-11 in bugzilla https://bugs.eclipse.org/532302

If we can find the appropriate artifact on maven central. Currently we have:

      <groupId>org.eclipse.platform</groupId>
      <artifactId>org.eclipse.osgi</artifactId>
      <version>3.13.100</version>

I tried changing the Required-Execution-Environment header in our osgi manifests to JavaSE-11, and ran the osgi unit tests. They actually worked with no errors. Somewhat confusing since release 3.13.100 from maven central predates any of the eclipse bugs that mention support for jdk-11.

@guw any advice?

@janbartel Do you have a pointer to the OSGi unit tests? Happy to take a look.

Hi Gunnar,

The osgi unit tests are here: https://github.com/eclipse/jetty.project/tree/jetty-10.0.x/jetty-osgi/test-jetty-osgi

To update to JavaSE-11, I changed this line in the jetty project's top level pom and rebuilt: https://github.com/eclipse/jetty.project/blob/jetty-10.0.x/pom.xml#L660

Are you running the Maven build with JDK 11 or are you using a toolchain.xml? I suspect that the tests will be executed with the Java running the build. Frankly, I don't know if Equinox needed special support for Java 11 execution environment. Most of the bugs I found are related to JDT and Java Development. We have a couple of JDK 11 issues with missing imports because of javax.xml stuff that has been removed.

@guw I'm running with jdk 11. Our pom also enforces use of jdk 11. So other users deploying into OSGi at the command line shouldn't experience any BREE problems if they just use jdk 11?

[guw]

No they shouldn't. Only if they run on a lower JDK.
