Description

Officially ServiceNow MID Servers only support our OpenJDK JRE from Madrid onwards. Madrid is the version when we first started shipping this JRE as part of the Installer, and was what all MID Server-related release testing was done with.

MID Server Installer	Java Runtime
<=Kingston	Oracle 1.8.0_152 JRE (8u152) is Supported and Distributed with the MID Server installer. Previously releases included 8u60, 8u40, 6u45 & 6u14 and were the 'supported version' at the time, and would have been upgraded along with the MID Server. Kingston Patch 14 was the final Patch to include an Oracle JRE.
London	No JRE is included in the full Installer ZIP file. The minimum supported Oracle JRE is version 1.8.0_152 or higher Java 8 family. Customers had to install this first as per our docs and would therefore have to accept the licence agreement for the free Oracle Java SE 8 JRE to do that in their own name. However, if the MID Server was installed <=Kingston, then an upgraded London MID Server will continue to use the Oracle JRE originally installed by ServiceNow. You could copy a Kingston /jre folder into a new London MID installation /agent folder, but keep in mind you cannot use a Jakarta /jre on your London MID as Jakarta shipped with version 1.8.0_60, which is too old for the London installer.
>=Madrid	A ServiceNow build of OpenJDK 1.8.0_181 JRE is Supported and Included. More recent MID Server versions may include later patches, or versions of this JRE. MID Servers installed before Madrid will have the Oracle JRE replaced by the OpenJDK JRE.

Applicable Versions

All, although primarily in relation to MID Server JRE changes in Kingston, London and Madrid.

Additional Information

A MID Server downgraded from Madrid to an earlier version will have the JRE replaced with the Oracle one again. During Madrid testing, it was found that a Kingston MID Server running an OpenJDK based JRE inherited from Madrid will be unable to upgrade again, due to errors detecting the JRE version, and blocking the auto-upgrade process (see PRB1319796, which was fixed before Madrid GA release).
