Jarek Gawor commented on GERONIMO-4525:
---------------------------------------

Here's a simple batch and Java code that I used to experiment to whether 
resetting ERRORLEVEL to 0 or calling is cmd /c exit /b %errorlevel%:

Test.java:
{code}
public class Test {

    public static void main(String [] args) throws Exception {
        System.out.println(args[0]);
        System.exit(Integer.parseInt(args[0]));
    }
}
{code}

Test.bat:
{code}
@echo off

@setlocal enableextensions

set foo=
echo %errorlevel%

java Test %1
echo %errorlevel%

@endlocal
echo %errorlevel%
{code}

Then when you execute Test.bat 0 or Test.bat 50 and check echo %ERRORLEVEL% 
after executing it you should see that the %ERRORLEVEL% is set to the right 
value without doing anything extra.

> There are multiple problems in the current Windows batch commands (including 
> geronimo.bat, startup.bat, etc.)
>  - It's not recommended to define an environment variable with the name 
> ERRORLEVEL. See [1].
>  - Set a value to ERRORLEVEL has no effect to the exit code of the batch 
> command (so the documented exit code "0" and "1" are not actually there).
>  - The value of the ERRORLEVEL variable will also get unset when the 
> "@endlocal" command is called.
