Quarkus integration issue

[Sbruk]

Hello,

I'm trying to integrate jazzer in my Quarkus project and I'm facing a problem with a very basic first test.
The stack is Quarkus LTS 3.33.3.1, OpenJDK Runtime Environment Temurin-25.0.3+9 (build 25.0.3+9-LTS) and Maven 3.9.16.

Here is a reproducer.
There is a basic service's method that returns reproducer-LocalDate.now()-<ARG> and I'm trying to fuzz it. The test is the following:

After setting JAZZER_FUZZ=1;JAZZER_MAX_EXECUTIONS=100000 and executing the test class, I get the following error:

The exact trace is:

java.lang.NullPointerException: Cannot invoke "java.lang.Integer.intValue()" because the return value of "java.lang.reflect.InvocationHandler.invoke(Object, java.lang.reflect.Method, Object[])" is null

	at jdk.proxy5/jdk.proxy5.$Proxy95.consumeInt(Unknown Source)
	at org.acme.service.QuarkusServiceTest.testFuzz(QuarkusServiceTest.java:27)

Let me know if you need more information.

Thanks
