Guice 4.0-beta leaked the maven metadata files for Guava when it was
repacked to a private namespace. This confuses Buck when creating a
combined JAR that has both Guice and Guava.
Guice also leaked the source files for javax.annotation into its
binary JAR files. Buck sometimes finds and extracts these source
files at compile time, creating duplicate versions of the classes.
