1) Can you clarify if you are profiling a java project or debugging a java project ?
2) Do you want to remove the VisualVM profiling from the IDE ? If yes then you can go to MyEclipse Configuration Center > Dashboard. Uncheck the ‘MyEclipse VisualVM Profiler’ , apply the changes and follow the wizard.
