Seems, but it is not :-) I started the Sling launchpad with Java 9 and the system bundle provides the following capabilities: osgi.ee; osgi.ee="OSGi/Minimum"; version:List="1.0, 1.1, 1.2", osgi.ee; osgi.ee="JavaSE"; version:List="1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 9", osgi.ee; osgi.ee="JavaSE/compact1"; version:List="1.8, 9", osgi.ee; osgi.ee="JavaSE/compact2"; version:List="1.8, 9", osgi.ee; osgi.ee="JavaSE/compact3"; version:List="1.8, 9" Note the 9 everywhere, following the version change in Java: $ /opt/jdk-9/bin/java -version java version "9" (snip) > I think you can generate the header then with the following bnd > instruction: http://bnd.bndtools.org/instructions/runee.html The way I read it, this instruction parses a string argument into an EE enum. That does not help us as we are using a 'plain' java version string, not a legal execution environment value. ----- I understand the desire to not reinvent the wheel, especially with infrastructure code. However, releasing this plugin unblocks us with testing for Java 9, which has further issues once we run the ITs. Releasing a version of this plugin does not mean we'll never revisit the solution. If there is something better, I'm happy to remove the plugin from our parent pom. But given that the code is there, it's small and self-contained I'm inclined just to use it for now, and when we have a better solution retire it.
