See Integrating Stash with Atlassian applications for information about supported versions of JIRA.

 

Key: (tick) = Supported  (warning) = Deprecated  (error) = Not Supported

Java

  

Oracle Java

(tick) 1.8
(warning) 1.7
(error) 1.6

  • We recommend using Oracle JRE 8, which you can download from the Oracle website.
  • For Java 8 we recommend 1.8.0u40+ to avoid critical defects in older versions.
  • Stash only requires the Java JRE, not the JDK.
  • For OpenJDK, download and install instructions for Linux flavors are athttp://openjdk.java.net/install/.
  • Note that the Stash installer will install a supported version of the Oracle Java JRE, which is only available to Stash, if necessary. See Running the Stash installer.
  • (error) OpenJDK >= 1.8u25 and < 1.8u40 are not supported due to a severe defect, Bug 1167153. This was fixed in 1.8u40.
  • (error) Support for Java 6 was removed in Stash 3.0, as previously announced.
  • (warning) Support for Java 7 is deprecated, and will be removed in Stash 4.0. See End of support announcements for Stash.

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.

OpenJDK

(tick) 1.8u0 - 1.8u20

(tick) 1.8u40+

(error) 1.8u25+
(warning) 1.7 
(error) 1.6

Operating systems

 

 
Apple Mac OS X(tick) (Evaluation only, not supported for production deployment)
  • 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 and sufficient free memory. See hardware requirements below.
Linux(tick)

Microsoft Windows

(tick) (Not supported for 500+ Enterprise tiers)

Databases

Microsoft SQL Server / Microsoft SQL Server Express

MySQL

(tick) 5.5.x
(tick) 5.1.x

(error) 5.7+
(error) 5.6.0 – 5.6.15

 

MySQL, while supported by Stash, is currently not recommended especially in larger instances, due to inherent performance and deadlock issues that occur in this database engine under heavy load.

Affected systems may experience slow response times, deadlock errors and in extreme cases errors due to running out of database connections. These issues are intrinsic to MySQL (no other database engine supported by Stash shares this behavior) and are due to the way MySQL performs row-level locking in transactions. See http://dev.mysql.com/doc/refman/5.0/en/innodb-deadlocks.html for some general information on this.

Stash does its best to work around the MySQL behavior - see issues STASH-4517, STASH-4701 and others for example. However, under very heavy load you will generally get better performance with any of the other database engines supported by Stash (such as PostgreSQL which is also freely available) than you will with MySQL.

  • (error) MySQL 5.6.15 and earlier: Note that Stash does not support versions of MySQL 5.6 earlier than 5.6.16 at all, because of bugs in its query optimizer (#68424, #69005). See Connecting Stash to MySQL for more information.

  • (error) MySQL 5.7+ is not supported.

  • (error) Git 1.7.1 is not supported.
  • (warning) Git 1.8.3.x has some performance regressions which may cause problems in Stash with large repositories

Hardware requirements

Stash needs a minimum of 720 MB of free memory to start up. Additional memory is required to support Git operations, depending on the number and frequency of Git operations and the number of users. See Scaling Stash for further discussion of hardware requirements.

Notes:

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.
