A DESCRIPTION OF THE PROBLEM :
Right now it is not specified and the stacktrace can be confusing:

JDK 11:
```
jshell> new Exception().printStackTrace((PrintStream)null)
| Exception java.lang.NullPointerException
| at Throwable.printStackTrace (Throwable.java:657)
| at Throwable.printStackTrace (Throwable.java:648)
| at (#1:1)
```

JDK 17:
```
jshell> new Exception().printStackTrace((PrintStream)null)

| at Throwable.printStackTrace (Throwable.java:668)
| at Throwable.printStackTrace (Throwable.java:659)
| at (#3:1)
```

JDK 19:
```
jshell> new Exception().printStackTrace((PrintStream)null)
