How to set the tmp directory for selenium-server-standalone

Question

I am running a selenium-server-standalone-2.39.0.jar on a Linux VM for running selenium tests in a headless way (xvfb + firefox).

While running, the Selenium server creates a lot of temporary directories and files in /tmp/ which are not deleted after the tests are finished.

The problem is that my /tmp/ disk is rather small and I would like to use /var/tmp for this purpose. However, I cannot find any way to do so.

Do you know a possibility?

Selenium uses the JVM java.io.tmpdir property for this:

java/client/src/org/openqa/selenium/io/TemporaryFilesystem.java:

  private static File sysTemp = new File(System.getProperty("java.io.tmpdir"));
  private static TemporaryFilesystem instance = new TemporaryFilesystem(sysTemp);

Set it by passing -Djava.io.tmpdir to the JVM, e.g.:

$ java -jar selenium-server-standalone-*.jar -Djava.io.tmpdir=/some/other/tmp
