Java10: Thread-local handshakes

As part of this feature, Java introduces a callback on threads without performing a global VM safepoint. This feature gives the ability to stop threads individually without having to perform a global virtual machine safe point.

 

What is safepoint?

A point during program execution at which all GC roots are known and all heap object contents are consistent. All threads must block at a safepoint before the GC can run.
