Opening a project for command line tool

My plugin is an ApplicationStarter (command line tool); the main() method is properly called but when I try to open a project as following:

ProjectManager.getInstance().loadAndOpenProject(projectFileName);

IDEA is opening a window (?) and I got the following exception:

2005-07-30 19:44:27,359 INFO - om.intellij.util.ProfilingUtil -

Am I doing something wrong? Is that normal that IDEA is opening a window? What is this error about profiling?
