      "message": "Fix detaching a debugger while threads are suspended.\n\nThe interesting part of this change is in \"thread_list.cc\".\n\nI\u0027ve done a TODO in TagFromClass, but haven\u0027t seen it make any practical\ndifference in a debugger. I also tightened up the types in GetThreadStatus\nwhile investigating the fact that we report some threads as \"RUNNING, SUSPENDED\",\nwhich makes no sense until you realize that TS_RUNNING corresponds to both\nour kRunnable thread state and our kNative thread state, the latter of which\nmay actually be a suspended thread.\n\nI\u0027ve also made us fail faster in the \"address in use\" jdwp failure case,\nand tidied up a bunch of the capitalization in logging.\n\nChange-Id: I0fe705791d07db31c4615addce44da4fdfbfd0d1\n"
