ColdFusion JDK Requirement

COLDFUSION 2018 HF1 and above

For Application Servers

On JEE installations, set the following JVM flag, "-Djdk.serialFilter= !
org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**", in
the respective startup file depending on the type of Application Server being
used.

For example:

Apache Tomcat Application Server:edit JAVA_OPTS in the 'Catalina.bat/sh' file

WebLogic Application Server:edit JAVA_OPTIONS in the 'startWeblogic.cmd' file

WildFly/EAP Application Server:edit JAVA_OPTS in the 'standalone.conf' file

Set the JVM flags on a JEE installation of ColdFusion, not on a standalone
installation.

COLDFUSION 2016 HF7 and above

This security update requires ColdFusion to be on JDK 8u121 or higher. Adobe
recommends that you must manually update your ColdFusion JDK/JRE to the latest
version. In case you do not update the JDK/JRE, simply applying the update
would NOT secure the server.

For Application Servers

Additionally, on JEE installations, set the following JVM flag,
"-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!
org.apache.commons.beanutils.**", in the respective startup file depending on
the type of Application Server being used.

For example:

On Apache Tomcat Application Server, edit JAVA_OPTS in the 'Catalina.bat/sh'
file

On WebLogic Application Server, edit JAVA_OPTIONS in the 'startWeblogic.cmd'
file

On aWildFly/EAP Application Server, edit JAVA_OPTS in the 'standalone.conf'
file

Set the JVM flags on a JEE installation of ColdFusion, not on a standalone
installation

COLDFUSION 11 HF15 and above

This security update requires ColdFusion to be on JDK 7u131 or JDK 8u121 or
higher. Adobe recommends that you must manually update your ColdFusion JDK/JRE
to the latest version. In case you do not update the JDK/JRE, simply applying
the update would NOT secure the server.

For Application Servers

Additionally, on J2EE installations, set the following JVM flag,
"-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!
org.apache.commons.beanutils.**", in the respective startup file depending on
the type of Application Server being used.

For example:

On Apache Tomcat Application Server, edit JAVA_OPTS in the 'Catalina.bat/sh'
file

On WebLogic Application Server, edit JAVA_OPTIONS in the 'startWeblogic.cmd'
file

On aWildFly/EAP Application Server, edit JAVA_OPTS in the 'standalone.conf'
file

Set the JVM flags on a JEE installation of ColdFusion, not on a standalone
installation
