Darren Hobbs: Third party code considered harmful

Darren Hobbs: Third party code considered harmful: "A good example of this in the Java world is log4J - many projects use it for their logging requirements, and its a good tool. However what most projects will do is use it directly, which means that virtually every class in the system will have a dependency on log4J. If a need arises that log4J can't handle, or a new version is released that changes some behaviour your project depends on, it can be a huge job to go through all your code making changes."
