It looks like software that you use does not support Multi-release jar files: https://openjdk.java.net/jeps/238
Multi-relese jars are very common now. If you use the latest version of that software, check its bugtracker and post a new issue in it, if such issue does not exist yet. You can remove META-INF/versions directory from H2's jar by yourself as a temporary workaround. It is used only on Java 9 and later versions. If you use a recent version of Java, you can replace classes in regular directories with modified versions from META-INF/versions instead. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
