I just updated my macbook from OS 10.6.3 to 10.6.8 (yes, I know it's very outdated). Now I have org.apache.catalina.startup.Bootstrap appearing in my dock, and I have no idea what it's doing there. It won't let me turn off or restart the computer while it's running.
How do I turn it off? Please keep in mind that I have zero experience coding with java, and will need someone to walk me through it step-by-step. Thanks.
