GraalVM

GraalVM Native Image is an ahead-of-time compilation technology that generates native platform executables.
Native executables are ideal for containers and cloud deployments as they are small, start very fast, and require significantly less CPU and memory.
Deploy native executables on distroless and even Scratch container images for reduced size and improved security.
With profile-guided optimization and the G1 garbage collector, native executables built with GraalVM Native Image can achieve peak throughput on par with the JVM.
GraalVM Native Image enjoys significant adoption with support from leading Java frameworks such as Spring Boot, Micronaut, Quarkus, Gluon Substrate, etc.

Issues encounters

Build time and resource consumption

really long build time (X times longer than traditional build)
- traditional build: ~15s
- native build: ~3m38s
native build takes lots of resources (CPU+RAM)
- sometimes, my IDE / teams are killed because the build is stressing my computer a lot
- sometimes, my whole computer freezes
no immediate feedback if something does not work in native mode because when we are developing, we are not constantly building the app in native
- newest version of GraalVM includes a faster compilation for development, hence not to be used for compiling for production

Native build errors encountered

UnsupportedFeatureException

I got the following error when trying to build the native app:

Error: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: Detected an instance of Random/SplittableRandom class in the image heap. Instances created during image generation have cached seed values and don't behave as expected.  To see how this object got instantiated use --trace-object-instantiation=java.util.Random. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image runtime by using the option --initialize-at-run-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.

According to the documentation (https://quarkus.io/guides/native-reference#build-time-vs-run-time-initialization), adding -Dquarkus.native.additional-build-args=“—trace-object-instantiation=java.security.SecureRandom”` can help use track where the usage of this class is located.

In this poc, it was used by:

annotations-service HTTP client
TempFileCreator.createTempFilePath
AWS SDK apache HTTP client

The fix suggested by the documentation is to not call to Random or SplittableRandom in static methods/constructors. Or add the following property in the application.properties to init at runtime instead:

# some errors may be detected when building the native image:
# see https://quarkus.io/guides/native-reference#build-time-vs-run-time-initialization
# and https://quarkus.io/guides/writing-native-applications-tips#delaying-class-initialization
quarkus.native.additional-build-args=--initialize-at-run-time=java.security.SecureRandom
ReflectionConfigurationFilesquarkus.native.additional-build-args=--initialize-at-run-time=java.security.SecureRandom

We can mitigate for our code in TempFileCreator, however, it’s not possible to change the behavior for libraries that we depends on… This is quite a drawbacks here.

Smallrye no Converter registered for class java.net.URI

The converter-worker is using a URI as property for com.bioserenity.converter.application.quarkus.config.aws.AwsProperties.S3#endpoint. It seems it’s not supported in native (don’t know why).

Mitigation

Transform into a String instead.

SdkClientException: Unable to load an HTTP implementation

When starting the app in native, I got the following error:

Mitigation

When building the AWS clients, we must set the HTTP client:

add dependency

<dependency>  
    <groupId>software.amazon.awssdk</groupId>  
    <artifactId>apache-client</artifactId>  
</dependency>

Configure clients:

SqsClient sqsClient = SqsClient  
        .builder()  
        .region(Region.of(sqsProperties.region()))  
        .httpClient(ApacheHttpClient.create())
        .build();
 
S3Client s3Client = S3Client  
        .builder()  
        .region(Region.of(s3Properties.region()))  
        .httpClient(ApacheHttpClient.create())
        .build();

There are conflicts on the okhttp clients… The one provided by the annotations-service does not match the one needed by the GraalVM/Quarkus to compile the project.

It’s the “incomplete classpath” issue mentioned above.
