Can this be:

java_files = [ "android/java/release_src/org/chromium/base/ManagedInstall.java"
]

if (is_debug) {
  java_files += [ "android/java/debug_src/org/chromium/base/Reflect.java" ]
}

No - the files with the same name are different (in release_src vs debug_src).

The idea is that the calling code can call ManagedInstall.initialize(), and when
not in debug mode the release_src version will just provide an empty function.

Whoops, n/m.
