eclipse - What does Egit mean with the number in parenthesis in Package Explorer -

What does this mean by EGIT when it displays a number in parentheses in the package explorer in front of the project name, and a source Name of the folder, but not anywhere below?

Note the example number (16):

I have checked a tag from GIT (Head Different State). I do not have any local changes - neither committed or disorganized.

If this is a matter of relevance, then this is the Gereit repository in Ellepsy Kepler SR1 (Build id: 20130919919)

and I under the configuration (I'm using the default) do not see a match with the team. GIT | Label decoration | Projects:

  {dirty: & gt;} {name} [{repository} {branch} {branch_status}]  

It is not from EGIT.

Note that this is also on src / main / java . I think it's from Findbugs or Checkstyle or any other plug-in.
