<h1 id="supported-environments">Supported environments</h1>
<p>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.</p>
<p>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, 13, ...).</p>
<p>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.</p>
