如果在suite的setup里面杀掉java进程：AutoItLibrary.Run | taskkill /F /IM java.exe
执行sikuli的关键字会报这样的错误：
Connection to remote server broken: [Errno 10061] No connection could be made because the target machine actively refused it
但是上次的java进程如果没有杀掉，robot framework控制台的日志出不来
那么，就在suite的teardown里面杀掉java进程：AutoItLibrary.Run | taskkill /F /IM java.exe
