One of my teachers just gave a lecture on the Java serialization API. FFS please don't https://www.infoworld.com/article/3275924/oracle-plans-to-dump-risky-java-serialization.html
You can teach me things that I have already known for 7 years, but please do not teach gaping security holes like this.
They'll probably also neglect to tell us about SQL injections, like when I was taught Java in high school a year ago.
