+Note: checking out 'origin/master'.
+
+You are in 'detached HEAD' state. You can look around, make experimental</span> <b>&lt;1&gt;</b><span>
+changes and commit them, and you can discard any commits you make in this
+state without impacting any branches by performing another checkout.
+
+If you want to create a new branch to retain commits you create, you may
+do so (now or later) by using -b with the checkout command again. Example:
+
+  git checkout -b new_branch_name
+
+HEAD is now at 619ccc9... Make ReflectorImpl use mailboxes
