YouDebug - a non-interactive debugger scripted by Groovy

http://youdebug.kenai.com/

 

YouDebug is an interesting approach to the problem of analyzing bugs that happen in a production environment. Instead of trying to reproduce the bug in a lab, YouDebug allows to write a groovy script that can set breakpoints and work with the state at the breakpoint, gathering data to find out the source of the bug.
