             Summary: Optimize local variables use
                 Key: JASSIST-194
                 URL: https://issues.jboss.org/browse/JASSIST-194
             Project: Javassist
          Issue Type: Enhancement
    Affects Versions: 3.17.1-GA
         Environment: n/a
            Reporter: Pawel Veselov
            Assignee: Shigeru Chiba

At this point, when javassist generates bytecode while compiling, the local variables are added each time a new local variable is declared.

It, however, can add up to a lot of waste when variables have a short life. I would imagine this can happen more in auto-generated source code.

It doesn't look easy, though, considering how compilation is done in one pass, and there is no way to swap out load/store instructions after the method is completed...
