I have just tested this with the current master and it appears to have already been fixed. I get:

james@james-ubuntu:~/jython2.7.1rc1/bin$ ./jython -m pip install --upgrade pip
Requirement already up-to-date: pip in /home/james/jython2.7.1rc1/Lib/site-packages

james@james-ubuntu:~/jython2.7.1rc1/bin$ ./pip --version
pip 9.0.1 from /home/james/jython2.7.1rc1/Lib/site-packages (python 2.7)

james@james-ubuntu:~/jython2.7.1rc1/bin$ echo pip > requirements.txt 

james@james-ubuntu:~/jython2.7.1rc1/bin$ ./jython -m pip install -r requirements.txt 
Requirement already satisfied: pip in /home/james/jython2.7.1rc1/Lib/site-packages (from -r requirements.txt (line 1))
