Affects: v6.0.11
Language: kotlin
Spring Boot: v3.1.3
When an application is packaged as a native binary, not all resource bundle files are available (only the default resource file).
I have the following resource files in src/main/resources:
\messages\
..+messages.properties
..+messages_de.properties
application.yaml
apring:
messages:
basename: messages/messages
encoding: UTF-8
RuntimeHints have been registered for the bundle:
class ResourceBundleRuntimeHints : RuntimeHintsRegistrar {
override fun registerHints(hints: RuntimeHints, classLoader: ClassLoader?) {
hints.resources()
// The application fails to start in native mode when this is not registered
.registerResourceBundle("sun.util.resources.LocaleNames")
// Application resource bundle
.registerResourceBundle("messages/messages")
// Hibernate validator and GraphQL extended validation
.registerResourceBundle("ValidationMessages")
}
}
This is registered in src/main/resources/META-INF/spring/aot.factories:
org.springframework.aot.hint.RuntimeHintsRegistrar=\
com.example.graph.nativex.ResourceBundleRuntimeHints
Reproducer: juliuskrah/graphql-demo.
Tests are passing in jvm mode gradle clean check.
The three tests that fail in native mode rely on the resource bundle file:
$ gradle nativeTest
(log output here)

Comment From: sdeleuze
I think what happens here is that for PropertyResourceBundle, GraalVM currently requires registering underlying resources for properties/XML files rather that the bundle name, and RuntimeHints API just follow this behavior as it generates resource-config.json interpreted by GraalVM.
I am going to raise that point to the GraalVM team to see there feedback, and comment here to confirm my understanding is correct and check with them if that deserves a GraalVM enhancement request.
In the meantime, registerPattern("messages/*") can be used to make your sample working (after adapting ResourceBundleRuntimeHintsTest) with the current behavior.

Thank you for getting back to me @sdeleuze; registerPattern(String) was already working for me until I discovered registerResourceBundle(String) from browsing the source code and I thought that makes for excellent documentation when the project grows out of hand 😄.

The GraalVM team feedback is that it should be supported, so please create an issue on https://github.com/oracle/graal/issues and they will handle it on their side. Thanks for raising this!
