Neo4j OGM Bolt driver exception in native mode (GraalVM Native image)

[sachinsudhi]

Expected Behavior

I am building an api connecting to a neo4j database using OGM bolt driver. I need to be able to build and run the application in native mode exactly like we run in regular JVM.

Current Behavior
The application is perfectly functional in regular JVM mode. When I build it using GraalVM native mode the driver class is not found/ recongnized. Also, please note that I have the required dependencies in my pom.xml. (Provided stacktrace excerpt below).

Possible Solution
Add support for OGM in native mode?

Thanks for your time reaching out @sachinsudhi. As I stated in April here quarkusio/quarkus#8530 (comment) Neo4j-OGM is not happening from our side in native GraalVM mode anytime soon.

The Java-Driver for which we provide the quarkus extension is tested on our side and ensured to work on GraalVM native.

We might gonna explore options with Spring Data Neo4j 6, that is to be released in autumn. The Spring team is working on native compilation and from our side, only the CypherDSL needs to be changed not to use method handles.

Thanks again.
