What it means

Thrown by parsePositiveIntegerOption when Integer.valueOf raises NumberFormatException because the option value is not a parseable integer. The catch block wraps it in this IllegalArgumentException.

Solutions

1. Provide a plain decimal integer string with no extra characters.
2. Strip whitespace/units from the value before passing.
3. Validate the value is numeric in the calling script before invoking the tool.

Example fix

// before
bsim control configure host --port abc
// after
bsim control configure host --port 5432

// Ensure the value is a clean integer string before launch.
String trimmed = portValue == null ? "" : portValue.trim();
if (!trimmed.matches("\\d+")) {
    System.err.println("Invalid integer for port: " + portValue);
    return;
}

try {
    launchable.parsePositiveIntegerOption(option, value);
} catch (IllegalArgumentException e) {
    if (e.getMessage().startsWith("Invalid integer value")) {
        System.err.println(option + " needs a plain integer, got: " + value);
    }
    throw e;
}

When it happens

Trigger: Passing a non-numeric or non-integer string such as `--port abc`, `--port 5432.0`, or `--port " 5432"` (line 375).

Common situations: Non-numeric config values, trailing whitespace or units (e.g. '5432 '), float strings, or locale-specific formatting.
