g_man1990,

It looks as though the JMH benchmarks are not easy to debug:

https://stackoverflow.com/questions/42698583/jmh-forks-threads-and-debug

It appears that the benchmark code is trying to launch a process similar to the java debugger (presumably so that it can obtain the information it needs). If you place a breakpoint at the new Runner(opt).run() line in the java program, you will be able to debug and step through the code until the benchmark tries to run that process. But this will conflict with the debug process already launched.

So, this isn’t a MyEclipse issue and you will have to seek assistance in other forums (like StackOverflow).

Sorry for the inconvenience.
