[rules-users] A question about use sliding window with and without entry point

[Yu Changyuan]

Confirmed, the problem not happen with 5.6.0-SNAPSHOT(see
https://github.com/yuchangyuan/drools-test1s/tree/drools-5.6.0-SNAPSHOT).

So, the bug is fixed and I am a little curious which commit fix the problem.
