I do not think so. Thomas reported that Jacl scripts were
getting 3-4 times slower with the 1.2 tree. A little debug
info could not cause a slowdown like that. Besides, the
-O flag to javac does not really do much to make Java
programs faster (aside from removing debug info). I have
not been able to reproduce this, so I am not really sure
there is a problem. If someone can show me a script that
runs slower with the 1.2 version of Jacl, I will take
a look at it again.
