Scanner input not working in Java Platform Shell

### Apache NetBeans version

Apache NetBeans 13

### What happened

Java platform shell (Jshell) on Netbeans 13 not responding when I use Scanner.

It's already mentioned in Jira: https://issues.apache.org/jira/browse/NETBEANS-3855
and also asked in Stackoverflow: https://stackoverflow.com/q/60146438/2147347

### How to reproduce

Open java platform shell: Tools -> Java Platform Shell

write a simple input command:
```
Scanner a=new Scanner(System.in);
a.nextInt();
```

### Did this work correctly in an earlier version?

No

### Operating System

Windows

### JDK

11.0.12

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else


### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

Start by reproducing the issue from Tools -> Java Platform Shell on Windows with the Scanner and nextInt() snippet, then review the linked Jira issue NETBEANS-3855 for existing investigation. Done means Scanner input is accepted and nextInt() responds normally in the Java Platform Shell.
