# This test case reveals a corner case that will break vndk-indirect
# computation. To reproduce the case, the following condition must be
# satisfied:
#
# 1. libA depends on libB.
# 2. libA is a vndk-fwk-ext.
# 3. libB is an outward-customized vndk which depends on non-AOSP libC.
#
# Both AOSP libA and libB will be added to vndk-core. But,
# unfortunately, libA will be resolved to libB in vndk-fwk-ext and this
# will break the vndk-indirect computation because libC is not in
# generic references.
