Groovy why do you suck so badly?

I have had it. I've tried it. I hate it. I hate the hype. I hate the people who use it. I hate all of it. I'm going going back back to Java Java.... Check out this exception:

GroovyCastException: Cannot cast object '54' with class 'java.lang.String' to class 'java.math.BigDecimal'

I NEED a BigDecimal. Do I seriously have to cast the class to an int first? What good is groovy if it can't figure such a thing out. It wastes way more time dealing with absolute BS things like this than to actually write Java. Groovy isn't even a real language. Just a bunch of template hacks on Java. I'm over it. I'm going back to Java.
