ART: Switch to name-based IMT hashing Use a hash scheme based on the name. This keeps IMT slots stable when dex tables change. This incurs a severe performance penalty for computing the slot. Measurements on host degraded from 30ns to an average of 85mus. However, calls in compiled code will not incur this overhead. Added a test comparing similar interfaces in similar dex files.
