@gsandrew Yeah pretty much the springloaded project had its support dropped, I think the only reason it got to JDK8 was a community member(David Estes I believe) upgraded it. Some people have tried the
http://hotswapagent.org/ with mixed results I was never able to get it to work with the project I was working on.
The one thing that I did get working on was JRebel, which is expensive, but in my opinion, it came with its own trade-offs. At the time I was working on a very large project that took between 8 and 12 minutes to compile and run from a clean, with JRebel it took twice as long. Granted this project had dozens of files over 4000 lines and one file over 11,000. The Groovy compiler slows down exponentially if you have files over 3 or 4 thousand lines of code.
What I did to work around this was to set breakpoints in IntelliJ and use the Expression Executer window to write/test code, and then when I had it working the way I wanted it put it in the code, restart once, and test just to double check.
