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 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 (ie: 11, 15, ...).

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) JDK14 JDK15
v 0.19.0 March 2020 No No Yes (*2)
v 0.20.0 April 2020 Yes Yes Yes

v 0.24.0 January 2021 (*1) Yes Yes No Yes

Notes:

  • (*1): These OpenJ9 releases are expected, in line with our support statement.
  • (*2): These OpenJ9 releases are the feature releases that support only the new OpenJDK release.

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/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

Important: If you obtain pre-built binaries from AdoptOpenJDK.net, platform support might vary, depending on their build environment. Check the AdoptOpenJDK Platform support matrix.

OpenJDK 8 binaries are supported on the minimum operating system levels shown in the following tables:

Linux® x32 x64 ppc64le Z31 Z64
CentOS 6.10 Y Y N N N
CentOS 7.6 Y Y Y N N
Red Hat Enterprise Linux (RHEL) 6.10 Y Y N N N
RHEL 7.6 Y Y Y Y Y
SUSE Linux Enterprise Server (SLES) 12 Y Y Y Y Y
Ubuntu 16.04 Y Y Y N Y
Ubuntu 18.04 Y Y Y N Y

Note: Not all of these distributions are tested, but Linux distributions that have a minimum glibc version 2.12 (x) or 2.17 (others) are expected to function without problems.

Windows® x32 x64
Windows 10 Y Y
Windows Server 2012 R2 Y Y
Windows Server 2016 Y Y
Windows Server 2019 Y Y
macOS® x64
OS X® 10.9.0+ Y
AIX® ppc32 ppc64
AIX 7.1 TL4 Y Y
AIX 7.2 Y Y

When public support for an operating system version ends, OpenJ9 can no longer be supported on that level.

OpenJDK 11

Important: If you obtain pre-built binaries from AdoptOpenJDK.net, platform support might vary, depending on their build environment. Check the AdoptOpenJDK Platform support matrix.

OpenJDK 11 binaries are supported on the minimum operating system levels shown in the following tables:

Linux (Note 1) AArch64 (Note 2) x64 ppc64le Z64
CentOS 6.10 N Y N N
CentOS 7.6 Y Y Y N
Red Hat Enterprise Linux (RHEL) 6.10 N Y N N
RHEL 7.6 Y Y Y Y
SUSE Linux Enterprise Server (SLES) 12 N Y Y Y
Ubuntu 16.04 Y Y Y Y
Ubuntu 18.04 Y Y Y Y

Notes:

  1. Not all of these distributions are tested, but Linux distributions that have a minimum glibc version 2.12 (x) or 2.17 (others) are expected to function without problems.
  2. Only limited support for the 64-bit ARM architecture is currently available. For a list of known issues, see the Release notes for the latest version of Eclipse OpenJ9.
Windows x64

AIX 7.2 Y

When public support for an operating system version ends, OpenJ9 can no longer be supported on that level.

OpenJDK 15

Important: If you obtain pre-built binaries from AdoptOpenJDK.net, platform support might vary, depending on their build environment. Check the AdoptOpenJDK Platform support matrix.

OpenJDK 15 binaries are supported on the minimum operating system levels shown in the following tables:

Linux (Note 1) AArch64 (Note 2) x64 ppc64le Z64
CentOS 7.6 Y Y Y N
RHEL 7.6 Y Y Y Y
