'GraalJSEngineFactory could not be instantiated' on JDK22

[dmercuriali]

Hi,

we are using org.graalvm.js:js and org.graalvm.js:js-scriptengine 23.0.4 and I was doing some tests on jdk22.
The engine fails to initialize due to a removed method in java 22 sun.misc.Unsafe.ensureClassInitialized

java.util.ServiceConfigurationError: javax.script.ScriptEngineFactory: Provider com.oracle.truffle.js.scriptengine.GraalJSEngineFactory could not be instantiated

If you want to use JDK 22+ then I suggest you to try newer versions (23.1.x or 24.0.x). Feel free to check this POM file to see what Maven artifacts are needed?
