Is Groovy syntax an exact superset of Java syntax?

Question

Being a Java programmer, I don\'t really have a Groovy background, but I use Groovy a lot lately to extend Maven (using GMaven). So far, I could use all the Java code I need

Answer 1

It isn't.

My favorite incompatibility: literal arrays:

String[] s = new String[] {"a", "b", "c"};

In Groovy, curly braces in this context would be expected to contain a closure, not a literal array.
