Subject: [PATCH JGIT] Method invokes inefficient new String(String) constructor
Date: Thu, 19 Mar 2009 10:15:58 +0100	[thread overview]
Message-ID: <49C20D4E.5020203@gmail.com> (raw)

>From FindBugs:
Using the java.lang.String(String) constructor wastes memory because
the object so constructed will be functionally indistinguishable from
the String passed as a parameter. Just use the argument String directly.
