  • Stash only requires the Java JRE, not the JDK.
  • For Oracle Java, we recommend using Server JRE 7, which you can download from the Oracle website.
  • For OpenJDK, download and install instructions for Linux flavors are at
  • Once Java is installed, you will need to set the JAVA_HOME environment variable, pointing to the Java root directory. See Installing Stash on Windows or Installing Stash on Linux and Mac for details.

Pre-installed Java on some AWS EC2 Linux instances might be installed with a subset of features. See SSH server fails to start on AWS EC2 instance for more information.

Operating systems

  • Stash is a pure Java application and should run on any platform, provided all the Java requirements are satisfied.
  • In production environments Stash should be run from a dedicated user account.
  • Although Stash can be run in virtualised environments, Atlassian is not yet able to provide technical support for performance-related problems in a virtualised environment. If you do chose to run Stash in a virtual machine, please ensure that you choose a VM with good IO throughput.

Hardware requirements

See Scaling Stash regarding the hardware requirements for your Stash installation.


Deploying multiple Atlassian applications in a single Tomcat container is not supported. We do not test this configuration and upgrading any of the applications (even for point releases) is likely to break it.

Finally, we recommend not deploying any other applications to the same Tomcat container that runs Stash, especially if these other applications have large memory requirements or require additional libraries in Tomcat's lib subdirectory.
