> Can you please include more detail on how it fails currently? I assume it's some kind of deserialization error? You are right. The root cause is deserialization error. Currently, the type of collection used by ```Log4jController#getLoggers ``` (a MBean object) is scala collection (```toList.asJava```) rather than java collection. Hence, the profiler has to load scala library (scala-library.jar) to deserialize the binary to origin scala collection. For example, if I don't add scala library to JMC's classpath, JMC fails to deserialize the attribute of ```Log4jController``` and it shows "N/A" instead. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
