Hi:
The java.lang.ref.ReferenceQueue used synchronized and wait keyword. It should be avoided inside VM. mrp uses private final LightMonitor lock = new LightMonitor(); 

I've changed code, and it passes fop now.

Hi Da,

I was using source code from http://download.java.net/openjdk/jdk6/

I am going to update the library to the newest jdk6 library.

It is very possible to miss initialize classes, etc. The project is
really in early stage: you can build the boot image and run simple
hello world, and a few benchmarks, that's it.

I will check the problem you mentioned. I was using BaseBaseImmix
configuration when I tested OpenJDK port.

Regards.
