The exception implies that we weren't able to find the android.os.Build class in the heap dump, which is surprising.

@dvdface Yes I'd love a heap dump: py.ricau at gmail

Note: we should probably support the case of no Build class anyway, i.e. be able to run a JVM heap dump through shark-cli even if that yields nothing. Or at least error our "no build class, is this an Android heap dump?"
