How to escape * multiply symbol in bash after compiling a kotlin program to java jar that takes args[0] and prints it in the console?

Question

My bash version

$ bash --version
GNU bash, version 4.4.23(1)-release (x86_64-pc-msys)

My java version

$ java --version
openjdk 13.0.1 2019-10-15
OpenJDK Runtime Environment (build 13.0.1+9)
OpenJDK 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)

My kotlinc version

$ kotlinc -version
OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.
info: kotlinc-jvm 1.3.50 (JRE 13.0.1+9)

What I tried

$ echo *
chap_six.kt clean.sh hello.jar hello.kt README.md start.sh

$ echo \*
*

My simple print program

// hello.kt
fun main(args: Array<String>) {
    println(args[0])
}

After compiling my simple print program

kotlinc hello.kt -include-runtime -d hello.jar

I expect to see the * symbol printed in the console when running the java .jar

Here's what I get

$ java -jar hello.jar *
chap_six.kt

$ java -jar hello.jar \*
.git

$ java -jar hello.jar "*"
.git

$ java -jar hello.jar "\*"
\$Recycle.Bin

I tried to apply what is suggested in this answer but it failed too

My `hello.sh`

#!/bin/bash
FOO="*"
set +f
GLOBIGNORE=*
java -jar hello.jar $FOO

and the attempt

$ ./hello.sh
.git

My `hello2.sh` also fails

#!/bin/bash
FOO="*"
set -f
java -jar hello.jar $FOO

And the attempt

$ ./hello2.sh 
.git

My shopt looks like this

@LinosaysReinstateMonica yes I updated my question with the new failed attempts — Julien Reszka, Jan 09 '20 at 09:59

@LinosaysReinstateMonica I tried both set -f and set +f GLOBIGNORE it doesn't work with the java program, I updated my question with the failed attemps — Julien Reszka, Jan 09 '20 at 10:10
Sorry, for those of us who are thick, could you make it clearer what your *desired* result actually is? — Gem Taylor, Jan 09 '20 at 11:21
@LéaGris I updated my answer with the output of shopt and set -o — Julien Reszka, Jan 09 '20 at 12:16
@GemTaylor I expect to see the * symbol printed in the console when running the java .jar with the * symbol as param. I want to know what is the input required for it to understand that I want to put the star symbol in the program — Julien Reszka, Jan 09 '20 at 12:16
Try `java -jar hello.jar '\*'` (that is, with single quotes) — pepoluan, Nov 21 '22 at 12:07

Not a solution but a mean to frame the source of the issue.

Lets create hello.sh in Bash to compare how it handles the arguments array.

#!/usr/bin/env bash
# hello.sh
echo "$1"

Now create a test.sh to compare the output of same hello in Kotlin and Bash:

#!/usr/bin/env bash

for arg in '*' '\*' "'*'" '"*"'; do
  kotlinout="$(java -jar hello.jar $arg)"
  bashout="$(bash hello.sh $arg)"
  if [ "$kotlinout" = "$bashout" ]; then
    comp='are same';
  else
    comp='DIFFERS !!'
  fi
  printf 'Argument: %s\tKotink and Bash outputs %s\n' "$arg" "$comp";
  printf 'Kotlin output: %s\n' "$kotlinout";
  printf 'Bash output: %s\n' "$bashout";
done

Here is what it does in my environment:

$ bash test.sh 
Argument: * Kotink and Bash outputs are same
Kotlin output: chap_six.kt
Bash output: chap_six.kt
Argument: \*    Kotink and Bash outputs are same
Kotlin output: \*
Bash output: \*
Argument: '*'   Kotink and Bash outputs are same
Kotlin output: '*'
Bash output: '*'
Argument: "*"   Kotink and Bash outputs are same
Kotlin output: "*"
Bash output: "*"
