Rascal Shell stacktrace differs between repl and command line execution

[Tillaert]

Describe the bug

When printing out a stack trace, in the event a Rascal program terminates with an exception being thrown, the stacktrace of Rascal Shell (executed directly from the command line) differs from the stacktrace of the console/repl.

To Reproduce

Steps to reproduce the behavior:

Given a small test program:

module TE

import IO;

int f2(int i) {
	throw "Intentional Error";
}

void main(str args = [])
{
	println(f2(1138));
}

Executing it from the repl, gives this stac trace:

PS C:\Users\Tillaert\projects\test\src> java -jar C:\Users\Tillaert\Downloads\rascal-0.18.2.jar
Version: 0.18.2

rascal>main();
|file:///C:/Users/Tillaert/projects/test/src/TE.rsc|(51,19,<6,7>,<6,26>): "Intentional Error"
        at f2(|file:///C:/Users/Tillaert/projects/test/src/TE.rsc|(27,47,<5,0>,<7,1>))
        at main(|file:///C:/Users/Tillaert/projects/test/src/TE.rsc|(111,18,<11,1>,<11,19>))
        at $shell$(|prompt:///|(0,7,<1,0>,<1,7>)ok
rascal>

However, when executing the rascal code directly from the command line, the Rascal stacktrace is truncated (only showing the error) and a Java stack trace is shown instead:

Expected behavior

I would expect that, at least the complete rascal stack trace would be displayed. It would be nice, when no error occurs in the Java code itself, no Java stack trace is displayed (this adds noise to the output). The rascal runtime should still exit with a non-zero exit code.
