Spring Boot 3 fails to generate native image when having Avro as a dependency - spring

Question

I'm running ./gradlew nativeCompile to generate a native image on a project that has implementation("org.apache.avro:avro:1.11.1") as a dependency, with the following exception:

The exception happens in BindingReflectionHintsRegistrar.shouldSkipMembers(...)--> type.getCanonicalName():
private boolean shouldSkipMembers(Class<?> type) {
return type.getCanonicalName().startsWith("java.") || type.isArray();
}
The type that generates the NullPointer is class org.apache.avro.JsonProperties$1.
How can this be fixed?

Answer 1

This particular NullPointerException has been solved in this issue, the fix has been released with Spring Framework 6.0.3.
