Optimizing ConstantPoolGen

Hi folks,

I'm getting into compiling my own little scripting language into Java byte
code. Short experimentation with both Javassist and BCEL led me to use BCEL.

Just a quick question: Has anyone looked into optimizing constant lookups
in ConstantPoolGen (e.g. addInteger)? Right now, they are just scanned
linearly every time.

Many greetings,
Stefan

I would guess not. PRs (with tests) are welcome in GitHub.
