Lambda expression classes in GraalVM reflection configuration

[Eng-Fouad]

I am trying to run JDBI library in Quarkus native mode. By including all classes that are accessed via reflection to reflection-config.json, I was able to run it successfully.

However, I still got this exception (as warning) at runtime upon calling:

Jdbi jdbi = Jdbi.create(agroalDataSource).installPlugin(new SqlObjectPlugin());

I tried adding the lambda expression class to reflection-config.json but that didn't solve it:

  {
    "name" : "org.jdbi.v3.core.statement.CachingSqlParser$$Lambda$1a0f8d592d890e8f26473320a5cdb05c88cf7099",
    "allDeclaredConstructors" : true,
    "allPublicConstructors" : true,
    "allDeclaredMethods" : true,
    "allPublicMethods" : true,
    "allDeclaredFields" : true,
    "allPublicFields" : true,
    "queryAllDeclaredConstructors" : true,
    "queryAllPublicConstructors" : true,
    "queryAllDeclaredMethods" : true,
    "queryAllPublicMethods" : true,
    "allDeclaredClasses" : true,
    "allPublicClasses" : true
  }

I got this warning message at generating native image:

Warning: Could not resolve org.jdbi.v3.core.statement.CachingSqlParser$$Lambda$1a0f8d592d890e8f26473320a5cdb05c88cf7099 for reflection configuration. Reason: java.lang.ClassNotFoundException: org.jdbi.v3.core.statement.CachingSqlParser$$Lambda$1a0f8d592d890e8f26473320a5cdb05c88cf7099.

How to include lambda expression classes into reflection-config?
