com.yourkit.probes.builtin.AwtEvents
Description
This built-in probe records AWT/Swing events longer than 0.3 second, which can cause UI irresponsiveness.
Problem detection: irresponsive UI
If a long operation is performed directly in the event queue thread, UI may become irresponsive: do not redraw, do not accept user input etc.
Good practice is to perform long operations in a separate thread, and use the event queue to present prepared results only.
For analysis of the results provided by this probe, select AWT event in probes table and apply CPU usage estimation.
