I am trying to understand the behaviour in the following code examples

groovy:000> [][0] ===> null groovy:000> [][0..0] ERROR java.lang.IndexOutOfBoundsException: toIndex = 1 at groovysh_evaluate.run (groovysh_evaluate:2) ... groovy:000>

Why does the first code segment return null, whereas the second throw an IndexOutofBoundsException. My expectation was for this to be consistent with the outcome of the first code fragment.

I am using the groovy compiler 2.1.4

Thanks.

[][0..0] must be calling List.subList( from, to ) which throws an AIOOBE. the [][0] calls a groovy's getAt(ix) method wich is safe

btw [].first() results also in NoSuchElementException

I think, that the behavior is quite consistent
