		"description": "Hello !\r\nWe were trying to log some handled exceptions with the APM module for Android (apm.logHandledException( ) ) and we just noticed whenever we try to instantiate a Javascript Error in Android , this always comes out as an empty object ( { } ), where as, when doing the very same thing in iOS will work with no issues.\r\nThis however, has only been tested in simulators/emulators.\r\n\r\nIt was also tested with Ti SDK 7.x and 6.x. In both cases new Error seems to be broken in Android, but working in iOS.\r\n\r\n\r\nSample app: https://propelics.box.com/s/q8nryev5c6fc8eqzl3rem21jjd792vj4\r\n{code}\r\nvar e = new Error('Some error');\r\nvar e2 = new Error();\r\n\r\nconsole.log('e=' + JSON.stringify(e));\r\nconsole.log('e2=' + JSON.stringify(e2));\r\n{code}\r\n\r\nSteps to reproduce:\r\n1) Take a look at index.js and see how we're trying to instantiate 2 Error objects, then printing them in the console.\r\n2) Run the application in Android (we've been using emulators with Android 6.0 and 7.1.1)\r\n3) When the application launches look at the console. The printed logs will be empty objects:\r\n[INFO] e={}\r\n[INFO] e2={}\r\n4) Re-run the app in iOS\r\n5) Observe the console output and how actual error objects will be printed:\r\n[INFO] e={\"line\":55,\"column\":19,\"sourceURL\":\"file:///Users/user/Library/Developer/CoreSimulator/Devices/63801195-0FE5-4A3F-9615-F1ABAAB35DFC/data/Containers/Bundle/Application/D4F143DB-E591-4258-9567-6D294EBEB265/BlankApp.app/alloy/controllers/index.js\"}\r\n[INFO] e2={\"line\":56,\"column\":20,\"sourceURL\":\"file:///Users/user/Library/Developer/CoreSimulator/Devices/63801195-0FE5-4A3F-9615-F1ABAAB35DFC/data/Containers/Bundle/Application/D4F143DB-E591-4258-9567-6D294EBEB265/BlankApp.app/alloy/controllers/index.js\"}\r\n",

The most important property is {{stack}}, which holds the message and stacktrace of the error and would likely hold all the info you'd want. They also typically have a {{message}} property which is just the message passed in (so here it'd be {{'Some error'}}).\r\n{code:javascript}\r\nTi.API.error(error.stack);\r\n{code}\r\n\r\nWe also added a {{nativeStack}} property for any under the hood java stacktrace on Android (if we had one), which will land in 7.2.0. The relevant tickets are: TIMOB-25963\r\n and TIMOB-25965 (though I'm not sure they were updated to note the new property).\r\n\r\nSo, long story short: the properties on Error are not enumerable by default on V8 due to complying more strictly to the ES5 spec, but it's relatively easy to just log the {{stack}} property if it's available, and fall back to the {{message}} property if not.\r\n\r\nBut we may want to alter our JSON.stringify impl on Android to specifically handle this case.",
