Jenkins kills Tomcat or other Java process after job ends

Recently, I was adding new application deployment to Tomcat server that was started by Jenkins. Process was starting nicely, but was stopping at the end of the job. The only clue was log record:

Service exit with a return value of 143

This issue can be easily solved by adding -Xrs to JAVA_OPTS. Option description can be found at http://docs.oracle.com/javase/6/docs/technotes/tools/windows/java.html.

Running Selenium with Groovy on PhantomJS

There is script that runs and takes snapshot of PhantomJS with Selenium:

@Grab("com.github.detro.ghostdriver:phantomjsdriver:1.0.1")

import org.openqa.selenium.*
import org.openqa.selenium.phantomjs.PhantomJSDriver
import org.openqa.selenium.remote.DesiredCapabilities

new PhantomJSDriver(new DesiredCapabilities()).with {
    manage().window().setSize(new Dimension(1028, 768))
 get("http://www.google.com")
 getScreenshotAs(OutputType.FILE).renameTo("screenshot.png")
 quit()
}

Running Selenium with Groovy on Firefox

There is small script to run and take screenshot in Firefox with Selenium from Groovy:
