Hello all, I'm working with a custom processor, and among other things, I added to the init() method two things : I register an MBean and I start a new thread. When testing I noticed that I got 2 MBeans registered and 2 threads created. When digging a bit further, I saw that one MBean and one thread were linked to a processor whose id was "mock-processor", and when looking at Nifi's source code it looks like this is part of the initialization of all processors (https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-framework-nar-utils/src/main/java/org/apache/nifi/init/ProcessorInitializer.java), but I'm not sure, and I didn't find anything about that in the documentation. I have two questions: Is this standard behaviour? Are all processors initialized this way or is there something weird going on with the one I'm using? If this is standard behaviour, am I doing something wrong or against best practices by doing this kind of things (registering MBean, starting new thread) inside the init method? Where should these things go? Cheers!
