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:

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.

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
