I am trying to use jemini jpa on Java 9 (on Java 8 everything is ok) but get the following exception. How to fix it?

I haven't tried it on JDK 9 yet, but have you tried the OSGi framework on JDK 9 without Gemini JPA? It's possible that the framework is not JDK 9 compatible.

Hi Michael

Thank you very much for your answer. I was afraid that this forum is dead and I am alone with my problem. Could you say, where will discussion about Gemini JPA take place if this forum is closed?

Now , to topic. I use Oracle JDK.
/opt/jdk-9/bin$ ./java -version
java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)


Osgi framework works and I use org.apache.felix.framework-5.6.8.jar.

In truth I am not maintaining the project anymore, and have not found anyone to take it over so you kind of are on your own at this point...
I try to answer any posts on this forum, but as you can tell there are not many at all, and looking back there have only been a few people over the last few years, and only you for the last year.

If you have tried Felix on that JDK 9 build and found that it works, and have also verified that EclipseLink also works, then there might well be some changes needed to make Gemini JPA work on JDK 9. If you are interested in pursuing it I would suggest stepping through to find where the incompatibilities might lie.

I see. Ok, could you say if official last code is here https://github.com/eclipse/gemini.jpa or I should download it from somewhere else?

By the way, do use use StackOverflow? Or maybe you can be found in some mailing list? I am asking for future, maybe your help will be required when this forum dies.
