Summary: ArrayIndexOutOfBoundsException in SimpleString -
getChars() method
Key: ARTEMIS-5690
URL: https://issues.apache.org/jira/browse/ARTEMIS-5690
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.31.2, 2.43.0
Environment: openjdk version "21.0.8" 2025-07-15
Reporter: Mikhail Titov
I have found an ArrayIndexOutOfBoundsException bug as a result of fuzz-testing
SimpleString - getChars() method.
Run the following code to reproduce:
{code:java}
import org.apache.activemq.artemis.api.core.SimpleString;
import java.util.Base64;
public class ArrayIndexOutOfBoundsBug {
public static void main(String[] args) {
String Base64String = "AA==";
Base64.Decoder decoder = Base64.getDecoder();
String str = new String(decoder.decode(Base64String));
SimpleString simpleStr = SimpleString.of(str);
simpleStr.getChars(0, 1, new char[0], 0);
}
}{code}
