  "message": "Remove String.setCharAt().\n\nThe internal API String.setCharAt() breaks the assumption\nthat strings are really immutable. That in turn breaks\nstring compression invariants - compressible strings must\nbe compressed. This CL removes the String.setCharAt() API.\n\nThe method was used only in String.replace(char, char)\nwhen we found a match, copying the string on first match.\nInstead, introduce a new native method that does the whole\nreplacement with a single call when we find the first match.\n\nStringReplaceBenchmark results on Nexus 6P, lower is better:\n  timeReplaceCharNonExistent/EMPTY   41.93 -\u003e   38.25 (-9%)\n  timeReplaceCharNonExistent/L_16   114.90 -\u003e   95.09 (-17%)\n  timeReplaceCharNonExistent/L_64   419.97 -\u003e  320.65 (-24%)\n  timeReplaceCharNonExistent/L_256 1667.01 -\u003e 1091.25 (-35%)\n  timeReplaceCharNonExistent/L_512 3253.50 -\u003e 2075.62 (-36%)\n  timeReplaceCharRepeated/EMPTY      41.93 -\u003e   39.58 (-6%)\n  timeReplaceCharRepeated/L_16      114.87 -\u003e   95.40 (-17%)\n  timeReplaceCharRepeated/L_64     1267.29 -\u003e  704.32 (-44%)\n  timeReplaceCharRepeated/L_256    5139.14 -\u003e 1361.80 (-74%)\n  timeReplaceCharRepeated/L_512   10787.81 -\u003e 2338.41 (-78%)\n  timeReplaceSingleChar/EMPTY        41.78 -\u003e   37.16 (-11%)\n  timeReplaceSingleChar/L_16        449.54 -\u003e  497.51 (+11%)\n  timeReplaceSingleChar/L_64        942.08 -\u003e  891.35 (-5%)\n  timeReplaceSingleChar/L_256      2756.18 -\u003e 2174.64 (-21%)\n  timeReplaceSingleChar/L_512      5489.91 -\u003e 3983.32 (-27%)\n\nTest: testrunner.py --host\nTest: run-libcore-tests.sh --mode\u003dhost\nTest: testrunner.py --host with string compression enabled.\nTest: run-libcore-tests.sh --mode\u003dhost with string compression enabled.\nBug: 31040547\nChange-Id: I9cf0d5457182f0a33ca8251c29931d3eb624ae07\n",
