Caused by: java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy

Introduction:
The java.lang.ArrayStoreException is a common issue encountered in Java programming, often signaling an attempt to store an object of an incompatible type in an array. When this error message specifically mentions sun.reflect.annotation.TypeNotPresentExceptionProxy, it typically implicates problems related to annotations within your codebase.

Understanding the Error:
The error suggests that there might be discrepancies between the annotations used in the code and the availability of referenced classes or types during runtime. This inconsistency can lead to the mentioned exception and hinder the smooth execution of your Java application.

Steps to Resolve the Error:

1. Verify Class Availability:
   Begin by ensuring that all classes referenced by annotations are accessible within your project’s classpath. Missing classes can disrupt the annotation processing mechanism and trigger the ArrayStoreException.
2. Check Dependencies:
   Thoroughly examine your project dependencies and libraries for any missing or incompatible versions. Even a single misconfigured dependency can propagate the error throughout the application.
3. Library Version Compatibility:
   Confirm that the versions of all utilized libraries align harmoniously with each other. Mismatched versions can introduce unexpected behaviors, including annotation-related errors.
4. Reflection Handling:
   If your code employs reflection to access annotations, double-check that the reflection logic adequately handles exceptions. Proper exception handling prevents runtime issues like TypeNotPresentExceptionProxy from halting program execution.

Illustrative Code Sample:

import java.lang.annotation.*;

// Define a sample annotation
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@interface SampleAnnotation {
    String value();
}

// Example class demonstrating annotation usage
public class AnnotationExample {

    // Method annotated with SampleAnnotation
    @SampleAnnotation("Sample Annotation Usage")
    public void annotatedMethod() {
        // Method implementation
    }

    // Main method to demonstrate reflection-based annotation processing
    public static void main(String[] args) {
        // Retrieve annotations using reflection
        try {
            Annotation[] annotations = AnnotationExample.class
                    .getMethod("annotatedMethod")
                    .getAnnotations();

            // Process annotations
            for (Annotation annotation : annotations) {
                if (annotation instanceof SampleAnnotation) {
                    SampleAnnotation sampleAnnotation = (SampleAnnotation) annotation;
                    System.out.println("Annotation Value: " + sampleAnnotation.value());
                }
            }
        } catch (NoSuchMethodException | SecurityException e) {
            e.printStackTrace();
        }
    }
}

Another Solution:

was to remove

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxrs</artifactId>
    <version>3.1.11</version>
</dependency>

and include

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web-services</artifactId>
</dependency>

Conclusion:
In conclusion, resolving the java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy error in Java applications demands meticulous examination of annotation usage, class availability, dependency configurations, version compatibilities, and reflection handling. By adhering to the outlined steps and ensuring coherence across your project, you can effectively mitigate the occurrence of this error and enhance the robustness of your Java applications.
