I would like to announce the HotswapAgent version 1.0
http://hotswapagent.org/mydoc_release_notes_10.html
, that includes many new features and fixes. Project DCEVM (
http://github.com/dcevm/dcevm/releases
) from version 8u112 includes crucial fixes that make hotswap on Java8 much more stable especially on eclipse and netbeans platform (IntelliJIdea has been already OK).
