Indeed. You have to compile with javac with the --release 8 option, which is new starting from JDK 9. That will create class files that use only Java 8 language features and link against the Java 8 standard library instead of the Java 11 one. > Would it be possible to update jdk8 in Debian to support that? Even if it were (which I doubt), the Java 8 runtime (standard library) does not contain many functions added, so it will not work. bye, //mirabilos -- tarent solutions GmbH Rochusstraße 2-4, D-53123 Bonn • http://www.tarent.de/ Tel: +49 228 54881-393 • Fax: +49 228 54881-235 HRB 5168 (AG Bonn) • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg _______________________________________________ Mailing list: https://launchpad.net/~openjdk Post to : openjdk@lists.launchpad.net Unsubscribe : https://launchpad.net/~openjdk More help : https://help.launchpad.net/ListHelp
