This article specifies the Liferay support policy for the GlassFish application server. It addresses support coverage unique to GlassFish and not already covered by the generic Application Server Policy.
For more information please see the Application Server policy.
Oracle no longer offers commercial support for GlassFish, but it’s still in development as an open source product. As such, GlassFish remains a compatible application server. Liferay isn't responsible for providing commercial support for the Glassfish application server itself.
Glassfish is not a compatible application server for any versions of Liferay DXP.
