I just upgraded from 3.3 to 3.4, and can't figure out how to get "real-time" java validation. I get validation as I type for simply things like syntax errors. But errors for non-existent methods are not shown until a build/validate is run. Like this:

A a = new A();

If a.foo() does not exist, I don't see the syntax error in eclipse until I run validate. Does anyone know how to make that real-time as I type?
