Bug 26547 Automatic closing of strings is not smart enough
Trying to add strings around an existing identifier is highly annoying when the Automatically close Strings option is set. For example, when I try to add Strings around: System.out.println(a) before a then I get two quotes. I suggest the rule to not close a string when there is a letter that belongs to an identifier to the left or right.
