      "message": "Deoptimization-based bce.\n\nA mechanism is introduced that a runtime method can be called\nfrom code compiled with optimizing compiler to deoptimize into\ninterpreter. This can be used to establish invariants in the managed code\nIf the invariant does not hold at runtime, we will deoptimize and continue\nexecution in the interpreter. This allows to optimize the managed code as\nif the invariant was proven during compile time. However, the exception\nwill be thrown according to the semantics demanded by the spec.\n\nThe invariant and optimization included in this patch are based on the\nlength of an array. Given a set of array accesses with constant indices\n{c1, ..., cn}, we can optimize away all bounds checks iff all 0 \u003c\u003d min(ci) and\nmax(ci) \u003c array-length. The first can be proven statically. The second can be\nestablished with a deoptimization-based invariant. This replaces n bounds\nchecks with one invariant check (plus slow-path code).\n\nChange-Id: I8c6e34b56c85d25b91074832d13dba1db0a81569\n"
