Description

This is how Groovy 1.5.1 deals with array assignments:

String[] _abc = [ "A", "B", "C" ] as String[]

assert _abc instanceof String[] == true
assert _abc instanceof Object[] == true

Object[] _xyz = _abc

assert _xyz instanceof Object[] == true
assert _xyz instanceof String[] == false

And this is Java:

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

assertTrue(abc instanceof String[]);
assertTrue(abc instanceof Object[]);

Object[] xyz = abc;

assertTrue(xyz instanceof String[]);
assertTrue(xyz instanceof Object[]);
