JDK 17+ Support Considerations

The following considerations must be taken into account when using EJB Features on JDK 17+:

  • If using a Java SE client for remote EJB lookups, add the --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.management/javax.management=ALL-UNNAMED --add-opens=java.management/javax.management.openmbean=ALL-UNNAMED JVM arguments to the list of startup arguments of the client.

  • If using the appclient script, add the following options to the VMARGS environment variable: --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.management/javax.management=ALL-UNNAMED --add-opens=java.management/javax.management.openmbean=ALL-UNNAMED

  • Note: these options are the minimal set for a rudimentary client on Java 17 or 21, more advanced clients may require additional options.
