  2. Issue 302: Include js-scriptengine and use upper case 'G' in 'Graal.js'. 

    This dependency is also required:
```
    <dependency>
      <groupId>org.graalvm.js</groupId>
      <artifactId>js-scriptengine</artifactId>
      <version>22.3.3</version>
    </dependency>
```

The following arning is observed:
```
[engine] WARNING: The polyglot context is using an implementation that does not support runtime compilation.
The guest application code will therefore be executed in interpreted mode only.
Execution only in interpreted mode will strongly impact the guest application performance.
For more information on using GraalVM see https://www.graalvm.org/java/quickstart/.
To disable this warning the '--engine.WarnInterpreterOnly=false' option or use the '-Dpolyglot.engine.WarnInterpreterOnly=false' system property.

The configuration file appears to be case sensitive.
Use `Graal.js` with an upper case `G` rather than a lower case `g`.
