void.class is not recognized by groovy

try this:

C:\>groovy -e "println(int.class)"
int
C:\>groovy -e "println(void.class)"
script_from_command_line: 1: Unknown type: "void" at line: 1 column: 9. File: script_from_command_line @ line 1, column 9.
1 Error

void.class is a valid class in Java, and should be that in groovy, too.

I know Void class is accessible, but this is not adequate, as void.class and Void.class are different (return false for equals method), just like int.class and Integer.class are different.
