String.replaceAll() in EMFTVM maps to the Java String.replaceAll(). EMFTVM transparently maps each Java method that is not explicitly defined in the VM's built-in library. I had added regexReplaceAll() as a built-in function, but I had not remapped replaceAll() to Java's String.replace(). Java methods that are transparently mapped are translated to native method invocations by EMFTVM's JIT compiler, so they are more efficient. You can use String.replace() in EMFTVM to get the behaviour of regular ATL's String.replaceAll(). I will document this difference on the EMFTVM wiki page.
EMFTVM lazy rules return their default output element when they have no "do" block. When there is a "do" block, you must indeed specify the returned element manually. I was under the impression that this behaviour was the same as in regular ATL. If this is not the case, please file a bug against EMFTVM.
Another "gotcha" is that EMFTVM is more strict about reading from the output model (forbidden in regular ATL too, but not always checked). Also, EMFTVM uses its own immutable collections framework, so you cannot do this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=405587. There may be more "gotchas" that I haven't thought of or am not yet aware of. Feel free to report them as you discover them! I will fix them where appropriate, or at least document them.
Cheers,
Dennis
