[ANNOUNCE] LaTTe Java Virtual Machine

The LaTTe virtual machine has been released. It is a freely available
virtual machine intended to execute Java classes. It can be obtained
from <http://latte.snu.ac.kr/>.


LaTTe is a research prototype for the study of dynamic (just-in-time)
compilation techniques. Among its features are:


* A fast and effective JIT compiler with
    - efficient register mapping and allocation
    - "traditional" optimizations (e.g., common subexpression elimination)
    - object-oriented optimizations (e.g., customization and specialization)


* A limited framework for adaptive compilation, which is currently
    based on method run counts.


* A reasonably fast bytecode interpreter, intended to be used with
    the adaptive compilation framework.


* Lightweight monitors.


* On-demand translation of exception handlers.


* A fast, non-incremental garbage collector.


As a result, the performance of the LaTTe JVM is competitive with that
of commercial JVMs, such as Sun's Hotspot and JDK 1.2 production release,
even without exploiting adaptive compilation.


LaTTe runs on top of Solaris 2.5 or higher on UltraSPARCs. Currently,
there are no plans to port LaTTe to other platforms.


LaTTe was developed by the MASS Laboratory at Seoul National University
with sponsorship from the IBM T.J. Watson Research Center.
