             Summary: Compile 10.16 into Java 17 bytes code so that it won't run on earlier platforms
                 Key: DERBY-7137
                 URL: https://issues.apache.org/jira/browse/DERBY-7137
             Project: Derby
          Issue Type: Task
          Components: Build tools
    Affects Versions: 10.16.0.0
            Reporter: Richard N. Hillegas
            Assignee: Richard N. Hillegas


The 10.16 network server must be run with -Djava.security.manager=allow in order to enable the Java Security Manager over the objections of https://openjdk.java.net/jeps/411. The meaning of that flag has changed since Java 11. To minimize confusion, we want to prevent people from accidentally running 10.16 on Java platforms older than Java 17.
