  • Added support for virtual threads in JFR.
  • Integrated the recurring callback-based and the signal-handler-based execution samplers into JFR.
  • The recurring callback-based execution sampler is used by default.
  • The signal-handler-based execution sampler can be enabled via an option.
  • Added uninterruptible code to access Java-level stack frame information
  • Various bugfixes for JFR stack traces and execution sampling.

In a follow-up PR, I will do further cleanups (renaming and moving files/classes/methods).
