[rules-users] Sliding window of length (1) equals latest event?!

[radai]

I came across a very similar behavior, but as far as i can tell its far
worse: https://issues.jboss.org/browse/JBRULES-2862
in my case events just stay in memory forever (until the jvm dies). this
means any rule i've tried with 2 windows is a memory leak.
