commit 5a2e98fd78417c2a3b701b7efb83dffcfeb411e2
Author: John Sirois <john.sirois@gmail.com>
Date:   Sat May 9 22:43:57 2015 -0600

    Copy java-compiler in from twitter/commons.
    
    This ports the java-compiler used by pants but does not actually
    configure pants to use the ported Compiler.  That will come later
    after the tool is published:
    https://github.com/pantsbuild/pants/issues/1361
    
    The java-compiler in twitter/commons will be deleted after this tool
    is published and consumed by pants HEAD.
    
    Testing Done:
    CI went green here:
