Comment 8 for bug 1224481

Had the same problem like markshao and the solution is very simple. runIDE on Windows has the following lines at the end of the file:

"%JAVA_HOME%\bin\java.exe" %PARMS% -jar "%SIKULIX_HOME%sikuli-ide.jar" %SIKULI_COMMAND%

GOTO FINALLY
:STOPIT
echo.+++ ended with some errors
:FINALLY
ENDLOCAL

Here the exit value of the Java call is overwritten by subsequent echo call. It can be fixed by adding the line
EXIT /B %ERRORLEVEL%
at the very end of the file.
