Building an ARM version of pty4j

I have an ARM platform and I need to add pty4j.so to get IntelliJ to work right. This is a follow up my previous post where I thought the problem was system.out.println. As it turns out it is a missing compatible version of pty4j. After trying the things I found I have so far been unable to get anything to work. It is my guess I need to find the source for pty4j.so and compile it on my platform but I have been unable to find that. Can someone help me get an ARM compatible version of this library? TIA.
