Or some other service is. at org.openqa.selenium.server.SeleniumServer.start(SeleniumServer.java:473) at org.openqa.selenium.server.SeleniumServer.boot(SeleniumServer.java:281) at org.openqa.selenium.server.SeleniumServer.main(SeleniumServer.java:244) at org.openqa.grid.selenium.GridLauncher.main(GridLauncher.java:54)

if you get this and you don't see any process capturing port 4444 try this: http://localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer (might happen when you try to start selenium locally with java -jar)
