JavaFunctions in Symja 2.0.0

[wirker]

Hello Axel,

according to the docs the builtin JavaFunctions (like the J/Link function in Mathematica) seem to be supported in Version 2.0.0 of Symja when using a local MMA console.

I could not, however, get it to work. JavaNew["java.lang.String"] evaluates to itself. LoadJavaClass["java.lang.String"] brings up an exception:

java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')

Am I miss something like InstallJava[] or explicitly set AddToClassPath?

Best,

Stefan.

Fixed the issue in #543.

The setup needs to enable filesystem. If you want to have exact Mathematica syntax relaxedSyntax = false should be set:

        Config.FILESYSTEM_ENABLED = true; 
        boolean relaxedSyntax = false;

See refactored JUnit test:
