Mojo folks: The variable on this side is called "applicationContext" - is it
really an app context? The native code this calls into names it "activity".
Mixing these up is bad ;)

Yes, this code is wrong. This code has been forked from the mojo repo which has
evolved a lot since. In the mojo repo, this code is not passing an activity
anymore and this is not a problem anymore. I do not know what is the state of
this code in chromium. ben@ and sky@ will have more info than me, but I guess
that all of this code is just dead, as it is there to have a mojo content
handler for java, and I'm not sure Mandoline plan to use this.

             nativeInit(applicationContext, mojoShell.getAbsolutePath(),
                     parametersList.toArray(new String[parametersList.size()]),
                     cachedAppsDir.getAbsolutePath(),
