XMLDecoder in native image fails with ArrayIndexOutOfBoundsException #10509
Description
Describe the Issue
When trying to deserialize an XML representation of a Java Bean using java.beans.XMLDecoder, the native image fails with an ArrayIndexOutOfBoundsException.
The same code works well when packaged as a runnable Jar. However, it fails when run as a native image. I have also tried to include the bean class (test.Person) in reflect-config and also serialization-config hints.
Using the latest version of GraalVM can resolve many issues.
- I tried with the latest version of GraalVM.
GraalVM Version
Oracle GraalVM 21+35.1 (build 21+35-jvmci-23.1-b15)
Operating System and Version
Darwin Kernel Version 23.0.0
Troubleshooting Confirmation
- I tried the suggestions in the troubleshooting guide.
Run Command
./App
Expected Behavior
Person object is constructed successfully and the below string is printed
Hello from Person{firstName='John', lastName='Doe', age=50}
Actual Behavior
Running the native App results in error as below
java.lang.InstantiationException: com.sun.beans.decoder.JavaElementHandler

Steps to Reproduce
XmlDecoderTest.java

public class XmlDecoderTest {
public static void main(String[] args) {
System.out.println(decodeTestPerson());
}
public static String decodeTestPerson() {
XMLDecoder decoder = new XMLDecoder(new ByteArrayInputStream(getXmlEncodedPerson().getBytes()));
Object readObject = decoder.readObject();
Person decodedPerson = (Person) readObject;
return "Hello from " + decodedPerson;
}
private static String getXmlEncodedPerson() {
return """
