      "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"
