By default a plugin is launched on the AWT Event Dispatch Thread so GUI creation
can be done directly without invokeLater calls.
A common problem is that long process will actually lock the EDT and make GUI not responding.
A plugin implementing this interface will have both its run() methods called
in a separate thread but developer has to use invokeLater method
for GUI creation / modification. Also there is no more guarantee that plugin constructor is called
in the EDT (which is the case for default plugin).
