Aslak Knutsen commented on JBIDE-8548:
--------------------------------------

Something odd is happening when starting up Maven in debug mode.

{code}
mvn -Dmaven.surefire.debug test
{code}


Now, right clicking in eclipse will cause a strange lag/hang and all is very sluggish. This warning is shown in the Error log:

> It would be helpful if Eclipse could provide a 'debug as' with auto discover of local java processes, somewhat like jconsole does. Eclipse should also auto associate the debug session with the current project. 
> 'debug as' -> 'remote process x'
