      "message": "ART: Fix race in on-stack replacement\n\nThe expected sequence of events for on-stack replacement is:\n\n   1. Method goes warm, triggering enhanced profiling\n   2. Method goes hot, triggering method compilation\n   3. Method goes really hot, triggering an osr method compilation.\n   4. Interpreter polls for the existence of an osr entry point,\n      and transitons to compiled code if found.\n\nWe have a race problem if #2 and #3 happen closely together, and\nthe osr method compilation begins before the regular method\ncompilation.  In that case, the jit sees that the method is\nalready being compiled (the osr method - but it does not\ndistinguish the two), and discards the normal compilation request.\nSo, the osr version is compiled and the normal version is discarded.\nIn #4, the MaybeDoOnStackReplacement() check assumes that a normal\nversion of the compiled method must exist before doing an on-stack\nreplacement, so it keeps returning false.\n\nThis is why we were seeing sporadic timeout failures of\n570-checker-osr when the mterp fast branch profiling was\nintroduced.  The branch profiling performance enhancements\ngreatly reduced the time between #2 and #3, increasing the liklihood\nof losing the race.  Further, the new code clamped hotness to avoid\nwrap-around.  The race existed (and likely occurred) in the previous\nversion, but because hotness counters were allowed to overflow and\nwrap around you\u0027d eventually hit the threshold a second time and\ntry again - masking the problem.\n\nTip \u0027o the hat to Serguei Katkov for identifying the problem.\n\nA possible solution (taken in this CL) is to differentiate osr\ncompilations from normal method compilations.\n\nBug: 27939339\nChange-Id: I71044516b35dc69de9fc2d2a445e33809ac650ed\n"
