      "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"

Improve deoptimization so more JDWP\ntest cases are passing.\n\nRefactor exception debug posting, in particular improve reporting in the\ninterpreter. Improve class linker exception throwing so that broken dex files\nare more likely to be reported. Fixes the performance issue Bug: 8410519.\n\nFix some error reporting lock level errors for the large object space. Make\nfast object verification faster.\n\nAdd some debug mode robustness to finding dex PCs in GC maps.\n\nAdd printf attributes to JniAbortF and fix errors.\n\nExpand run-test 044 to test return behaviors and fix issues with not throwing\nappropriate exceptions for proxies.\n\nEnsure causes are reported with a class linker NoClassDefFoundError and JNI\nNoSuchFieldError.\n\nRemove unused debugMe and updateDebuggerFromCode.\n\nThere\u0027s a minor sizing tweak to the arg array builder, and an extra reference\narray check in the interpreter.\n\nSome clean-up of trace code.\n\nFix reg type cache destructor if it is called after the reg type cache is\nshutdown (as is the case in oatdump).\n\nChange-Id: I6519c7b35df77f978d011999354c864f4918e8ce\n"
