Michal Kordas fa102b60fa Use value of putIfAbsent to fix Findbugs violation, issue #778
Previously there was slight risk that returned value is not the one that is associated with the key in the map. This could happen if another thread inserted value to map between calls to `get` and `putIfAbsent`.

All violations of Findbugs rule [RV: Return value of putIfAbsent ignored, value passed to putIfAbsent reused](http://findbugs.sourceforge.net/bugDescriptions.html#RV_RETURN_VALUE_OF_PUTIFABSENT_IGNORED) are fixed.
