Fork from apache common bcel 6.0-SNAPSHOT project. Since nobody is maintaining BCEL project so far, and Lifecycle AOP project depends on BCEL 6.0 apis, so iMadz releases net.imadz version BCEL 6.0 internally. DO NOT USE it unless you tested all the 6.0 related apis you need. net.imadz will not be responsible for maintaining this library.

The newest version!
