Windows 10, VisualVM 2.0.7, JDK 8u291.

Opened the host VisualVM process, configured CPU sampler to "Profile only classes" javax.swing.*, set "Sampling frequency" to 20ms.

Started CPU sampling, displayed both "Forward calls" and "Hot spots" views. The "Forward calls" shows code from javax.swing.* (e.g. javax.swing.TimerQueue.run(), javax.swing.Timer.post()), but at the same time the "Hot spots" show no results, see the attached screenshot.

The expected and correct behavior is "Hot spots" view showing code from classes in the javax.swing package, like javax.swing.TimerQueue.run(), javax.swing.Timer.post() and other.
