Returns java.lang.IllegalArgumentException in ProcessBuilder.start()

Looking at the source code for ProcessBuilder, there is a method isQuoted that checks if a String argument is quoted and throws IllegalArgumentException if it is and a flag is checked.

private static boolean isQuoted(boolean noQuotesInside, String arg,
        String errorMessage) {
    int lastPos = arg.length() - 1;
    if (lastPos >=1 && arg.charAt(0) == '"' && arg.charAt(lastPos) == '"') {
        // The argument has already been quoted.
        if (noQuotesInside) {
            if (arg.indexOf('"', 1) != lastPos) {
                // There is ["] inside.
                throw new IllegalArgumentException(errorMessage);
            }
        }
        return true;
    }
    if (noQuotesInside) {
        if (arg.indexOf('"') >= 0) {
            // There is ["] inside.
            throw new IllegalArgumentException(errorMessage);
        }
    }
    return false;
}

The above is called from getExecutablePath, note the true flag

 boolean pathIsQuoted = isQuoted(true, path,
            "Executable name has embedded quote, split the arguments");

which is called inside the ProcessImpl constructor

String executablePath = getExecutablePath(cmd[0]);

where cmd is the array created from your list. Index 0 matches the executable (in your case the whole String). In the String you showed us, your executable is quoted (or at least starts with one), so the method will throw an IllegalArgumentException.

This is confirmed by your stack trace

at java.lang.ProcessImpl.<init>(ProcessImpl.java:69)

That means inside your constructor.

Split each argument in your command list as a separate String element in the list. Don't put quotes around the executable.
