25 b06Fixed
Description
Enable native access doesn't work with the source launcher if launching in a named module.

```
run:
    java \
      --enable-native-access=dev.mccue.sdl \
      -Djava.library.path=SDL/build \
      -XstartOnFirstThread \
      src/example/Main.java

WARNING: Unknown module: dev.mccue.sdl specified to --enable-native-access

Exception in thread "main" java.lang.ExceptionInInitializerError
    at dev.mccue.sdl/example.Main.main(Main.java:15)
Caused by: java.lang.IllegalCallerException: Illegal native access from: module dev.mccue.sdl

java --enable-native-access=ALL-UNNAMED -Djava.library.path=SDL/build -XstartOnFirstThread src/example/Main.java

Exception in thread "main" java.lang.ExceptionInInitializerError
    at dev.mccue.sdl/example.Main.main(Main.java:15)
Caused by: java.lang.IllegalCallerException: Illegal native access from: module dev.mccue.sdl
```

File tree looks like:

```
src/
  example/
    Main.java
  dev/
    mccue/
      sdl/
        ...
  module-info.java (dev.mccue.sdl)
```

Work-around: remove the `module-info.java` file to make the source launcher load the classes in the unnamend module and pass `--enable-native-access=ALL-UNNAMED` to the launcher as can be seen in the second example.
