ColdFusion JDK Requirement
COLDFUSION 2025 (version 2023.0.0.331385) and above
For Application Servers
On JEE installations, set the following JVM flag, “-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**;!org.jgroups.**;!com.sun.rowset.**; !com.mysql.cj.jdbc.interceptors.**;!org.apache.commons.collections.**; " 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 2023 (version 2023.0.0.330468) and above
For Application Servers
