  "message": "Add test runner support for context messages without location information.\n\nThe CFE implementation of \"why not promoted\" functionality for\nnon-promotion of `this` doesn\u0027t associate the context message with any\nlocation information, because there is no relevant location to cite.\nFor example, the output can look like this:\n\n    tests/language/why_not_promoted/this_error_test.dart:16:10: Error: Property \u0027isEven\u0027 cannot be accessed on \u0027int?\u0027 because it is potentially null.\n    Try accessing using ?. instead.\n        this.isEven;\n             ^^^^^^\n    Context: \u0027this\u0027 can\u0027t be promoted.\n    See http://dart.dev/go/non-promo-this\n\nThe test runner assumes that all messages have a location, so it\nwasn\u0027t picking up on this context message at all.  This CL avoids the\nproblem by having the test runner associate any location-less context\nmessage with the error above it.\n\n(Note that the analyzer doesn\u0027t have this problem; all of its context\nmessages have locations).\n\nChange-Id: Ied52daa8b0090f28617e7d3784233aa44dcc897a\nReviewed-on: https://dart-review.googlesource.com/c/sdk/+/195301\nReviewed-by: Bob Nystrom \u003crnystrom@google.com\u003e\nCommit-Queue: Paul Berry \u003cpaulberry@google.com\u003e\n",
