8902	[Patches] Small performance enhancements / coding style	shinigami	team	"Hi,
I am sending you patch with lots of small perf enhancements. It's based at the Idea static analysis and autocorrection, so it should not contains bugs. Changes are:

String comparison to """" => isEmpty()
coll.toArray(T[0]) -> coll.toArray(T[coll.size()])
append one char string -> append char
index of one char string -> index of char.
sb.append(s1+s2...) -> sb.append(s1).append(s2) ...
removed concats with empty strings

all are little changes but there are lots of them (and much more waiting:). I hope it will help."	enhancement	closed	minor		Core		fixed
