      "message": "ART: Remove incorrect HFakeString optimization\n\nSimplification of HFakeString assumes that it cannot be used until\nString.\u003cinit\u003e is called which is not true and causes different\nbehaviour between the compiler and the interpreter. This patch\nremoves the optimization together with the HFakeString instruction.\n\nInstead, HNewInstance is generated and an empty String allocated\nuntil it is replaced with the result of the StringFactory call. This\nis consistent with the behaviour of the interpreter but is too\nconservative. A follow-up CL will attempt to optimize out the initial\nallocation when possible.\n\nBug: 26457745\nBug: 26486014\n\nChange-Id: I7139e37ed00a880715bfc234896a930fde670c44\n"
