[keycloak-dev] Code style

I'm wasn't planing on having a lengthy discussion about code style. It's usually just a matter of personal preference and folks do get used to most things. Questions are: * Should we have a code style? * What IDEs are Keycloak devs using (I'm crossing my fingers everyone says IntelliJ) * Should we enable the checkstyle plugin? With regards to the actual style my first thought was to base it on WildFly code style (we do build on top of it after all). However, they do not have one for IntelliJ, which makes it a no go IMO. Further I don't particularly want to craft one (and try to get configs for IntelliJ match Eclipse, which also passes the checkstyle). So do anyone have suggestions of other projects we can borrow from? If we're going to incorporate a code style and re-format the current code case now is a very good time.
