Relying on the "Note: To specify an argument for a long option, you can use either --name=value or --name value." from [0] and assuming that `--module` is a long option (with `-m` being its short counterpart) I think I found an error in `java.exe`.

A minimal, complete and verifiable example at [2] -- which contains a README.md file with more details. Here's a gist:

Calling `java --module-path=lib --module=m/Main --help ...` sometimes fails to launch the JVM. The failure, if it occurs, expresses mostly via a silent exit of the `java.exe` program leaving a negative value in the "DOS shell" `ERRORLEVEL` environment variable. Seldom, a fatal error log is written to the current working directory.

The underlying reason seems to be an error in the calculation of the application argument count and index. The later reads: {{ AppArgIndex: -1 points to (null) }}

Work-around: omit the `=` (equals sign) after `--module` and the entry-point, here `m/Main`. This command line always gets the JVM up and running.

# Original Bug Description

Running the following command in a Windows (`cmd`) Console
```
java
  --module-path=
    bin/build/test/modules/it.jar;
    bin/build/main/modules;
    bin/build/test/modules;
    lib
--add-modules=it
--module=org.junit.platform.console
--select-module=it
```
the JVM sometimes(!) crashes.

## Reproduction

- Clone https://github.com/sormuras/bach-air - and switch to branch `JDK-8234076`
- Invoke `java src\build\Build.java`

Here's a GitHub Actions run showing the fatal errors on JDK 11 and 13: https://github.com/sormuras/bach-air/runs/300828140

Locally, I could reproduce similar errors using OpenJDK 11.0.2, 13.0.1 and also 14-ea+22 versions. Same, same for AdoptJDK 11.0.5 as can be seen here: https://github.com/AdoptOpenJDK/openjdk-build/issues/1378 -- this issue also contains some `hs_err_pid...log` files.


## Work-around

Use `--module org.junit.platform.console` -- without the `=` character.
