You misread the question.
I didn't mean (map even? (range 1000)), but a sequence of length 1000 where the elements are 1 * true, 2 * false, 3 * true, 4 * false and so on.
To compare it with what your code produces.
[true false false true true true false false false false ...]
[true false true false true false true false true false ...]
Edited for more clarity.

Right, sorry, in python that's something like:
from itertools import chain, repeat
chain.from_iterable([repeat(i % 2 != 0, i) for i in range(1,1000)])
IntStream.range(1,1001).flatMap(i -> Stream<Boolean>.generate( () -> (x & 1) != 0 ).limit(i))Doesn't that python code give you a list of 500,500 elements, rather than a list of 1000 elements as originally specified?

In both cases yes, and in both cases because I made the same stupid mistake when both languages have good means to do infinite streams and "take" equivalents. (And that's worse in the Java case, since I used those in the inner function but not the outer one.)
So, I think I need to take a break from comment-box programming for a while; its clearly not working out for me today.
So, again, python:
(If you insist on Java, its fairly straightforward, though not a one-liner AFAIK, using Java 8 generators.)
