just for the ps, JOE intends to work where developers don't have the time
nor the experience (i'm working on the second project to optimize and
believe
me their is work to do here). Moreover, JOE is very young (less than one
month),
so wait and see ;-)

ah.

Byte.parseByte(String) is faster, you avoid an allocation.
Byte.parseByte(String, 10) is even faster you avoid a method call

 int i = Integer.parseInt(s, radix);
 return  !(i < Byte.MIN_VALUE || i > MAX_VALUE)
is even more faster. you avoid a method call and and an exception

and yet I suggest to copy/paste the Integer.parseInt method and use your
own
by remove the exceptions to make it even more faster by removing yet
another
method call and exception.

>ps: don't have the time to make a patch (sorry)

I see. Time problem.

ps: If you should read something about Knuth, read only his most famous
quote. really.
With Joe, you're taking the optimization step by the wrong end IMHO
