Yes, I'm making progress on the jamvm for AmigaOS4.
I have found some pthread stuff that isn't implemented on AmigaOS4's implementation. For now its removed with #defines, which ofcourse doesn't work, but I atleast got it to run on the Miggy. I'm thinking of implementing the thread functionality with AmigaOS tasks. For now there are defines, #ifdef __amigaos4__, taking care of special stuff. Perhaps an entire new thread.c for AmigaOS...
Anyhow, I thought it might be good to compile for my x86 aswell, to see how its supposed to work. Then I also got to compile the classpath again.
Its rather encouraging actually being able to run something.
