Given that you are using javaSettings to load in JARs, if you use reloadOnChange=true, CF will not correctly update the classpath and load all the JARs. Credit for this find goes to Sandeep Paliwal. To correct this you will need to restart CF. (And obviously set reloadOnChange to false.)

It seems likely that the changes made for this issue are what caused bug CF-3956389. https://bugbase.adobe.com/index.cfm?event=bug&id=CF-3956389

Hi Sandeep and Ray, For me, CF11 Update 4 (build 11,0,04,293328) correctly reloads all the JARs after I update 1 or more of them. Example steps: 1) THIS.javaSettings = {loadPaths=[expandPath("./mylib")], loadColdFusionClassPath=false, reloadOnChange=true, watchInterval=5} 2) ./mylib contains HelloWorld.jar and WorldHello.jar. HelloWorld.jar contains hello() method that returns "Hello World". WorldHello.jar contains hello() method that returns "World Hello". 3) calling both hello() methods returns the correct strings 4) I update both hello() methods to return "Hello World 2" and "World Hello 2" respectively, then recompile both and place the updated .jar files in ./mylib 5) calling both hello() methods returns the correct/updated strings From the ticket's description, I thought one of the JAR files would not get reloaded after step #4. Could I please get more details on how to reproduce the issue? Thanks!, -Aaron

Also, I noticed reloadOnChange treats newly-added .class and .jar files differently. When adding additional .class files, they are picked-up w/o restarting the server or application. When adding additional .jar files, they are not picked-up until the application or server has restarted. Is it possible for reloadOnChange to not require an application restart in the case of additional .jars? Thanks!, -Aaron
