QEMU 6.1.0 monitor - type 'help' for more information
(qemu) quit
Working on running the tests. Now fixing on running GC cycle.
Fixing the @InterruptHandler annotation needed for the interrupt handling. Working through the ripples that it is causing.
More progress!
Need to fix the thread initialization and startup. Very close to time slicing

Was working on fixing how Classpath was compiled and built but came to the realization that the project needed to resync with the latest JikesRVM release and transition over to OpenJDK6. This is happening here: New JOE. Current state of this is it can build a non-working boot image. This will only work on a Mac OSX machine (will get to building from linux later). I will be developing and working in this new forked repo until I get JOE running the Dining Philosophers again. Then I will transition that new code into the JOE repo.
Finally got the Trace class added. Still have not found my bug happening first garbage collection. But from the tracing, the issue is not with the interrupts. Will probably start adding traces to the GC next.
Crash is happening in CharsetEncoder.encode(Ljava/nio/CharBuffer;)Ljava/nio/ByteBuffer;
