Supported environments
The Eclipse OpenJ9™ project source code can be built against multiple JDK levels starting with JDK8, so the question of support has a more complicated answer than at OpenJDK. Our community is committed to supporting JDK levels as long as they are supported at the OpenJDK open source project with a significant user base. Currently, Eclipse OpenJ9 produces a new release every quarter that can build against all JDK levels that are currently supported by the OpenJDK community. We are committed to accepting problem reports when using Eclipse OpenJ9 against a supported OpenJDK level, with fixes being delivered in each release of Eclipse OpenJ9.
In order to track the OpenJDK 6-month release cadence, OpenJ9 also produces two releases a year that support only a single JDK level. These releases will occur in March and September with the intention of supporting only the corresponding new OpenJDK feature release.
The following table summarizes which JDK levels are expected to be supported by which Eclipse OpenJ9 releases, along with projected release dates. All future dates and support expectations are predictions that might change depending on how the OpenJDK and OpenJ9 projects evolve over time. To keep this table concise, some rows and columns will be removed over time.
Eclipse OpenJ9 releases
| OpenJ9 release | Release date | JDK8 (LTS) | JDK11 (LTS) | JDK17 (LTS) | JDK21 (LTS) | JDK22 | JDK23 |

Notes:
- These future OpenJ9 releases are expected, in line with our support statement.
- These OpenJ9 releases are feature releases that support a new OpenJDK release only.
- These OpenJ9 releases support a new LTS OpenJDK release only.
For any issues or limitations of an Eclipse OpenJ9 release, read the release notes.
Platform support
The Eclipse OpenJ9 project is open to supporting any hardware or operating system platforms provided that we have community members available to maintain them. For practical reasons the Eclipse OpenJ9 JVM does not currently run on every platform.
OpenJDK 8
OpenJDK 8 binaries are expected to function on the minimum operating system levels shown in the following tables:
| Linux® | AArch64 | x32 | x64 | ppc64le | Z31 | Z64 |
|---|---|---|---|---|---|---|
| RHEL 8.8 | yes | no | yes | yes | no | yes |
| RHEL 9.2 | no | no | yes | yes | no | yes |
| Ubuntu 20.04 | yes | no | yes | yes | no | yes |
| Ubuntu 22.04 | no | no | yes | yes | no | yes |
Notes:
-
Not all of these distributions are tested, but the following distributions are expected to function without problems:
- Linux distributions that have a minimum glibc version 2.12 (x) or 2.17 (others)
- RHEL 9.2 and Ubuntu 22.04 distributions on AArch64 architecture
-
Support for OpenJ9 on CentOS 6.10 is removed from 0.46.0 release onwards. With the removal of support, the minimum glibc version (x) might change in future releases.
