The Thread.countStackFrames() method was changed to unconditionally throw an UnsupportedOperationException

The terminally deprecated method Thread.countStackFrames has been changed in this release to unconditionally throw UnsupportedOperationException. Remove the usage of this method in your application as it will now unconditionally throw an exception and will be removed in a future release.

This rule has an automated fix. Copy the custom configuration to your application build file to enable the fix automation.

This recipe removes the usage of this method in your application as long as the method is not assigned to a variable.
