Simplified code using Java 8 flatMap

This code solved one of the problems. It accumulates all the matches by looping over m.find(). The main problem is still not solved. It does not work on the result of the previous match.

So the result is wrong.

[Current Usage : init:2359296, used:13913536, committed:13959168, max:50331648|]
[Current Usage : init:2359296, used:13915200, committed:13959168, max:50331648|]
