Ahhaha. JBoss, the glorified web-app server that booted for tens of minutes. It was the peak of Java-based over-engineering.
To be fair, recent versions of JBoss/Wildfly removed a lot of the bloat and boot within seconds. Startup time is mostly due to application frameworks nowadays.
In a past life, I used to be almost ecstatic when a client would choose Tomcat over WebLogic or WebSphere, or whatever abomination of an app server they standardized on.
