I would wait till gcj+libgcj is stable to incorporate it into the tree. I can't get libcgj to compile over here and I tried updating libgcj a couple of times additionally it looks like it has had zero testing out on the field well at least the version available from cygnus cvs repository. We do need java vm experts and compiler people to hash out the problems with the currrent crop of Java to Native binaries compilers: 1. Electrical Fire http://www.mozilla.org/projects/ef 2. Japhar http://www.japhar.org The above compilers perform a java to native binary compilation . Whats the difference between this approach and JITs not much other than the compiler does more work to optmize the code for instance in the of EF it does a Chaitin-Briggs Register Allocation. It should be interesting comparing gcj and EF so far EF appears to generate the best code and I have tested against Kaffe and Japhar. This is going to be a good year for Freebsd !
