Aaron, The fix for bug # CF-4126642 is due to be released with next CF update. But you've mentioned that you can experience the issue even with the use of system setting: -Dcoldfusion.udf.reuseTagInstances=false Can you pls. share the relevant code extract with which you can experience the issue? The fix works with the test code shared in bug #CF-4120119.

attached file should break on second run, even with the reusetaginstances false in JVM args. cheers, Aaron.

Aaron, Thanks for sharing the test script. It works for me if I use the reusetaginstances JVM arg. It is possible that the buggy output you see are from pre-compiled classes, from the run you did without the JVM flag. Can you delete the classes from the cfclasses folder and try again. On a standalone instance of CF the folder is at <cf_root>/cfusion\wwwroot\WEB-INF\cfclasses folder . On a JEE deployment of CF it would be in <cfusion_war>\WEB-INF\cfclasses. If you want to avoid clearing the classes everytime, with any changes, you can uncheck the "save class files" option in the CF admin console > server Settings> Caching.

Aaron, Can you pls. try clearing the class files, as suggested in my previous comment.

clearing the class files has done the trick. i fear i may have only done that on my cf11 installation and not the cf2016. I've also checked the update and that works without the need for the reuseTagInstances JVM setting. seems all good now. cheers, Aaron.

Closing this as clearing classes fixed the issue.
