Error: Use -H:+ReportExceptionStackTraces to print stacktrace of underlying exception
Error: Image build request failed with exit status 1

I used --allow-incomplete-classpath because the Spark framework uses the SLF4J logging library only if it's available on the classpath, and I don't want to include it in my build.

Have you tried using -H:+TraceClassInitialization? It should show you where the object got instantiated.

I tried now. It told me to add --initialize-at-build-time=com.mysql.cj.jdbc.Driver, so I did. I now get another error (added -H:+ReportExceptionStackTraces to see the details, as it asked):

OK, this is now a separate issue. Assigning accordingly.

Can you try with the latest GraalVM built from master? Problems like interface com.mysql.cj.jdbc.JdbcConnection is not visible from class loader should have been fixed by a recent change by @eginez .

Are there any prebuilt binaries (aka "nightly builds") available or do I need to build it myself?

You would need to build it yourself for now. We plan to have nightlies in the near future. Instructions for building are here https://github.com/oracle/graal/tree/master/vm#vm-suite

Well it definitely got further this time. I used commit fa02eac and this JDK build (unpacking it and setting Contents/Home as JAVA_HOME did the trick).

I tried different combinations of --initialize-at-run-time=... and --initialize-at-build-time=... with classes related to the MySQL driver and this one gets farthest.

$ mx native-image -jar /Users/grishka/Documents/dev/smithereen/target/smithereen-jar-with-dependencies.jar --allow-incomplete-classpath --no-fallback --initialize-at-run-time=com.mysql.cj.jdbc.Driver --initialize-at-run-time=com.mysql.cj.jdbc.AbandonedConnectionCleanupThread --initialize-at-run-time=java.sql.DriverManager -H:+TraceClassInitialization

Tried adding --report-unsupported-elements-at-runtime hoping this code path won't actually end up being used because why would it need to load classes anyway and where are those classes going to come from. Compilation completes successfully but then the thing crashes at launch. Good news is that the crash isn't related to the MySQL driver, probably related to the use of reflection by some of the dependencies, and so is out of scope of this issue.

Maybe related quarkusio/quarkus#7936 ?
