      "message": "Basic structural redefinition support\n\nThis adds basic support for adding methods and fields to already\nloaded classes using redefinition. This \u0027structural class\nredefinition\u0027 is currently limited to classes without any virtual\nmethods or instance fields. One cannot currently structurally redefine\nmultiple classes at once nor will structural redefinition trigger the\nstandard redefinition events.\n\nAfter structural redefinition all references to the old class, and its\nfields and methods are atomically updated. Any memory associated with\nthe static fields of the old class is zeroed. Offsets for field access\nmight change.  If there are any active stack frames for methods from\nthe redefined class the original (obsolete method) code will continue\nto execute. The identity hash code of the redefined class will not\nchange. Any locks being held, waited or blocked on by the old class\nwill be transferred to the new class.\n\nTo use this feature the process must be debuggable and running with\n-Xopaque-jni-ids:true.\n\nFor device testing use a wrap.sh that adds the following flags:\n\n    \u0027-Xopaque-jni-ids:true -Xcompiler-option --debuggable -XjdwpProvider:adbconnection\u0027\n\nStructural redefinition only available using the\n\"com.android.art.UNSAFE.class.structurally_redefine_class_direct\"\nextension. This will not trigger the normal class-redefinition events.\nOnly one class may be redefined at a time.\n\nNB There are still some holes in this potentially allowing obsolete\nmethods/fields to be visible. Most notably during jni-id, MethodHandle\nand VarHandle creation as well as potentially other places in the\nruntime. These holes will be closed by later CLs. Until then the\nextension to access structural class redefinition will remain tagged\nas UNSAFE.\n\nTest: ./test.py --host --all-compiler\nBug: 134162467\n\nChange-Id: I825d3a4bdb9594c0147223ae69f433ce9bbfc307\n"

      "message": "JVMTI Force early return\n\nAdd support for can_force_early_return jvmti capability. This allows\none to force java frames to exit early. Exited frames have all of\ntheir normal locks released.\n\nWe implement this by modifying the existing method exit events to\nallow one to modify the exit value during the callback. This is used\nto implement ForceEarlyReturn by adding internal-only events that will\nchange the return value of methods once they return (using\nkForcePopFrame) avoiding the need to modify the actual interpreter\nvery deeply. This also makes it simple to continue to use the standard\ndeoptimization functions to force the actual return.\n\nIn order to simplify book-keeping the internal event is refcounted,\nnot associated with any specific jvmtiEnv, and only settable on\nspecific threads. The internal event is added by the ForceEarlyReturn\nfunction and then removed by the MethodExit event when we update the\nreturn value.\n\nBug: 130028055\nTest: ./test.py --host\nChange-Id: Ifa44605b4e8032605f503a654ddf4bd2fc6b60bf\n"
