Here's what I read about AgentSmith. 1. It has an implementation of the java.lang.instrument.Instrumentation interface and it also has a file monitor. 2. It has the ability to monitor predefined list of folders for changes to classes. It can also monitor jar files. 3. It needs atleast Java 5 to run.
There are a couple of problems that need to be addressed if we want to use this tool in ActiveMQ. 1. There doesn't seem to be any event notification mechanism built into this. So this tool will automatically reload the classes as soon as it identifies them as changed. So there is no mechanism by which we can stop our routes and then reload our classes, and then start the routes again. 2. It needs atleast Java 5 to run. I assume that we are planning to have this feature as part of 5.1.0 release of ActiveMQ. What JVM version is the minimum required for 5.1.0? If it has to run on 1.4.2, then Agent Smith is not an option for us. Please let me know your thoughts.
