Build time initialization of org.springframework.http.HttpStatus

[sdeleuze]

Since the introduction of Spring mechanism to make some fields constant at build time without having to use class build-time initialization (see this commit), org.springframework.http.HttpStatus (sources) is one of the few remaining Spring Framework class that requires build time initialization.

I suspect this is a GraalVM bug that could be fixed like done for DataSize. I suspect it is caused by this line that is not detected as safe by GraalVM so it requires manual build-time init which is unfortunate and something we would like to avoid.

Could you please check if that's fixable on your side (warning : for now, I will bring back a META-INF/native-image/org.springframework/spring-web/native-image.properties with Args = --initialize-at-build-time=org.springframework.http.HttpStatus so make sure to remove it to reproduce. Maybe just copy HttpStatus.java source code since it is pretty isolated.

Please tag this issue with the spring label.

Please find the stacktrace below:

If that can help, the related JAR can be found in https://search.maven.org/artifact/org.springframework/spring-web.

Thank you for reporting this, We will take a look into this and get back to you if needed.

@sdeleuze can you please check if the problem is still reproducible (with the latest daily build of GraalVM, as well as with GraalVM 22.2).

The call to Method.getDefaultValue from ReflectionDataBuilder.registerTypesForMethod was removed as part of the re-work of how we handle annotations in GraalVM 22.2. So at least the failing stack trace is no longer possible

[sdeleuze]

I confirm it works out of the box with GraalVM 22.2 and latest dev build without any --initialize-at-build-time configuration so you close this issue. Please set the milestone to 22.2.

Thanks for confirming that it works now!
