The reputation of "heavy" was hard-earned back in the bad-old-days (1.3 era) when EVERYTHING NEEDED to be written in java and the JVM still sucked. I, literally, had a party at work when we got our web app to three days of continuous uptime without an OOM error; nevermind that the early JIT (1.4 era) took 12+ hours to get "warmed up" and give peak performance. Don't misunderstand me- java's horribleness has given me a pretty nice career so, for that, I love it. For the years and years of broken promises- (OSGi without running out of PermGen? lol) I hate it. Java is not lightweight by any means; computers are just faster and have more memory.
