Description

Issue has been encountered with JDK 10.0.1 but it also exists when starting NetBeans with JDK 9.

Start JShell from Tools --> Open Java Platform Shell.

Issue the following commands:

[1]-> import java.util.Scanner;
[2]-> Scanner sc = new Scanner(System.in);
| sc ==> java.util.Scanner[delimiters=\p\{javaWhitespace}+][position=0][match valid=fa ...
[3]-> int a = sc.nextInt();

Executing, please wait

The user is waiting for ever and s/he cannot do anything. In JDK JShell the user can enter a value and the program continues. In NetBeans, this is not possible. A stop button is displayed, but clicking on it does nothing.
