3 years ago Hi @tylervz. My guess is this is an issue with the activemq-broker dependency. Could you try adding @TypeHint([org.apache.activemq.openwire.v10.MarshallerFactory]) in your project and seeing if that resolves this specific issue?

3 years ago Hi @elliottpope thanks for the suggestion. I'm a beginner with Micronaut so I'm not sure which class to decorate with @TypeHint. Because my project is a Picocli application, I added it above my main command class.
After adding the annotation @TypeHint([org.apache.activemq.openwire.v10.MarshallerFactory]) above my AmqJmsExampleCommand class definition, I'm unable to build the project:
error: illegal start of expression
@TypeHint([org.apache.activemq.openwire.v10.MarshallerFactory])

3 years ago Thanks @ilopmar
Now I'm getting the following error when I try to build the project:
amq-jms-example/src/main/java/amq/jms/example/AmqJmsExampleCommand.java:19: error: cannot find symbol
@TypeHint({org.apache.activemq.openwire.v10.MarshallerFactory})
^
symbol: class v10
location: package org.apache.activemq.openwire@tylervz my bad, I fired off the comment without actually writing valid Java code. The valid syntax for you is
@TypeHint({
org.apache.activemq.openwire.v10.MarshallerFactory.class
})and yes you can place this as a class-level annotation on your AmqJmsExampleCommand class. I'm just verifying on my machine whether this actually solves your problem, but this is what I would expect to solve the problem

3 years ago Ok, sorry this was a little late but my laptop is not powerful enough to run the native image compile.
@TypeHint(
value = { org.apache.activemq.openwire.v10.MarshallerFactory.class },
accessType = AccessType.ALL_DECLARED_METHODS)will solve you're problem. I have tested it out on my machine and everything is working perfectly. Sample log output after build/native-image/application -v is:
08:56:43.262 [main] INFO i.m.context.env.DefaultEnvironment - Established active environments: [cli]

@graemerocher if I add
@TypeHint(
value = { org.apache.activemq.openwire.v10.MarshallerFactory.class },
accessType = AccessType.ALL_DECLARED_METHODS)to the micronaut-jms-activemq-classic project, will all downstream projects not require this change? What I'm basically asking is whether the @TypeHint annotations cascade through dependencies

3 years ago Yes adding that to one of the classes and ensure the annotationProcessor "io.micronaut:micronaut-graal" is present in the dependencies will result in resolving the issue and it cascading to downstream projects

3 years ago @elliottpope sorry for my unresponsiveness; I was on vacation and just got back.
@TypeHint(
value = { org.apache.activemq.openwire.v10.MarshallerFactory.class },
accessType = AccessType.ALL_DECLARED_METHODS)Does indeed solve my problem. Thank you!
Task List
Steps to Reproduce
In the root directory of my example project, run the following commands
docker-compose upto run an AMQ broker../gradlew nativeImage(in a separate terminal) to build a native image of the application../build/native-image/application -vto run the CLI application and have it send a message to the broker.Expected Behaviour
A message should be sent to the AMQ broker. It works fine when running the application with the JVM (
java -jar build/libs/amq-jms-example-0.1-all.jar -v), however it throws an exception when running the Native Image.Actual Behaviour
The following error stacktrace is output when
./build/native-image/application -vis executedEnvironment Information
