Java 17

ActivePivot is compatible with Java 17.

Memory Monitoring​

Please note that to be able to be compatible with Java 17, we are no longer reporting the off-heap memory allocated with java's internal MBeans. Instead, you can use the newly created MBeans located in DirectMemoryMonitoring for the information you wanted regarding memory consumption from ActivePivot. Additionally, MAC can be used for deeper investigations.

JVM Options​

ActivePivot needs access to some internal modules to function properly, which are now protected in JDK 17, so the following argument is necessary:

--add-opens java.base/java.util.concurrent=ALL-UNNAMED

Additionally, to use Arrow as a source or an export format, the following option is required in JDK 17 by Arrow:

--add-opens java.base/java.nio=ALL-UNNAMED

This list is not exhaustive: we don't guarantee that it is enough to run ActivePivot. Our dependencies may require additional add-opens. Moving forward JDK versions, if you see in a stack trace that module XXX does not open YYY to an unnamed module, it means you are missing the JVM option --add-opens XXX/YYY=ALL-UNNAMED.
