I want to explore code paths in Cassandra database, so after getting the code from git and explore it a bit I noticed that it starts a daemon process when I run it from Eclipse. I supposed that when this happens, I can no longer use the IDE to follow where the code is. Due to another problem I created this question and the person who replied talked about a debug port. I'm not familiar with this concept, and after googling it, the best explanation I found was on Wikipedia:
Debug port is a port included in a device to simplify development and debugging, which is not necessary for normal functioning of it. Debug ports are usually not removed or disabled to avoid costs of design changes, and can be used by modders and hackers to get extra functionality.
Which doesn't provide a lot of information on what a debug port is. Anyone care to clarify, please?
