QuPath v 0.1.2 - logging

We are using QuPath-v0.1.2 and I am trying to setup logging within our extension where I want to log all errors to a log file. I currently did the setup but now QuPath crashes on startup. Do you have any suggestions? Is there a default way to set up logging within the program? Currently I am trying to get going with log4j - 2. Thanks in advance.

Hi, QuPath uses slf4j with logback. I think it should be possible to configure additional loggers.
