Duplicate entry in InnerClasses attribute in class file

Duplicate entry in InnerClasses attribute in class file

[Panicz Maciej Godek]

I have two entry points in GRASP
- one is for the client running in AWT,
and another one is for the client running in terminal:

https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/src/grasp-desktop.scm

https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/src/grasp-terminal.scm

They both work find, when run with appropriate scripts:

https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/grasp-desktop

https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/grasp-terminal

I wanted to merge them into a single entry point that would
decide whether the windowing system is available, and if so,
open AWT, and run in terminal otherwise.

So I wrote this module:

https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/src/grasp.scm

But when I try to run it - using the script
https://github.com/panicz/grasp-android/blob/master/stages/retreat/GRASP/grasp
- I get the following error:


Exception in thread "main" java.lang.ClassFormatError: Duplicate entry

What could be the reason for that error in this setup?
