A DESCRIPTION OF THE PROBLEM :
When closing the console in which jshell was started, it keeps running if it is currently executing something. This is not obvious to the user and not consistent with the behavior of `java.exe`.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Open "Command Prompt" (or PowerShell)
2. Start jshell
3. Execute code which runs in an infinite loop, e.g.: for (int i = 0;; i++) { }
4. Close the "Command Prompt" window

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
jshell is terminated
ACTUAL -
jshell keeps running in the background, this can be verified using the Task Manager

CUSTOMER SUBMITTED WORKAROUND :
Force terminate running code by pressing `Ctrl` + `C` before closing the console window
Or use the Task Manager or similar tools to terminate the jshell process afterwards

FREQUENCY : always
