Why are you spreading misinformation?
The GCJ runtime library does not use the LGPL. It uses the GPL, with an exception that permits linking against proprietary code. This is very friendly licensing IMO, and the FSF bashing is not warrented.
Those are great benchmarks to tune for in order to fool people. Here's a real world application, the Eclipse java compiler (called ecj here)...
This is a typical native ecj build (of rhino, in this example). I used the -repeat option to try to factor out any "fast start" advantage of the native executable.
gcj is no silver bullet, but there are definitely classes of useful programs that run almost three times faster with gcj than with the latest IBM JRE. The Eclipse java compiler is a good example of one (and this is after factoring out the fast start-up). Look here for a version you can check out and build with gcj.
Eclipse contains a java compiler which you can also compile as a standalone app with with gcj (see http://sources.redhat.com/rhug). The gcj-compiled compiler is almost three times faster than the latest IBM JRE run version.

...since gcj can build traditional shared libraries out of jar files. See http://gcc.gnu.org/java & http://sources.redhat.com/rhug
