Getting a Java class from Function.execute (LispObject introspection)

Hello,

I'm experimenting with compiling some code using javac and the following example:

https://github.com/slyrus/abcl/blob/master/examples/pure-lisp-to-java/Main.j...

I have one doubt regarding LispObject (what we get from Function.execute): I have read some introspection in the manual but my use-case is slightly different since the I will use the return value of the Lisp call and that value is actually a Java class (from a non-standard library which I use) that will be the return value of the main method of the Main class.

Is this feasible? Perhaps I'm missing something obvious, especially since my Java is hardly the strongest.

Best regards,
