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 a 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
