      "message": "GC clean up.\n\nGreater use of directories and namespaces.\nFix bugs that cause verify options to fail.\nAddress numerous other issues:\n\nGC barrier wait occurring holding locks:\nGC barrier waits occur when we wait for threads to run the check point function\non themselves. This is happening with the heap bitmap and mutator lock held\nmeaning that a thread that tries to take either lock exclusively will block\nwaiting on a thread that is waiting. If this thread is the thread we\u0027re waiting\nto run the check point then the VM will deadlock.\nThis deadlock occurred unnoticed as the call to check for wait safety was\nremoved in: https://googleplex-android-review.googlesource.com/#/c/249423/1.\n\nNewTimingLogger:\nExisting timing log states when a split ends but not when it begins. This isn\u0027t\ngood for systrace, in the context of GC it means that races between mutators\nand the GC are hard to discover what phase the GC is in, we know what phase it\njust finished and derive but that\u0027s not ideal.\n\nSupport for only 1 discontinuous space:\nCode special cases continuous and large object space, rather than assuming we\ncan have a collection of both.\n\nSorted atomic stacks:\nUsed to improve verification performance. Simplify their use and add extra\nchecks.\n\nSimplify mod-union table abstractions.\n\nReduce use of std::strings and their associated overhead in hot code.\n\nMake time units of fields explicit.\n\nReduce confusion that IsAllocSpace is really IsDlMallocSpace.\n\nMake GetTotalMemory (exposed via System) equal to the footprint (as in Dalvik)\nrather than the max memory footprint.\n\nChange-Id: Ie87067140fa4499b15edab691fe6565d79599812\n"
