Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Runtime, defect)

Description

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

Boot up the phone while running `adb logcat`. While booting to the homescreen/lockscreen, there will be several JavaScript warnings shown:

E/GeckoConsole(  308): [JavaScript Warning: "Could not map contract ID '@mozilla.org/gonk-gps-geolocation-provider;1' to CID fdffb9d1-0d61-4384-8993-206609376e73 because no implementation of the CID is registered." {file: "file:///system/b2g/distribution/bundles/libqc_b2g_location/chrome.manifest" line: 2}]
E/GeckoConsole(  308): [JavaScript Warning: "Could not map contract ID '@mozilla.org/ril;1' to CID {9A7181E8-E66A-11E1-B4A1-B1066188709B} because no implementation of the CID is registered." {file: "file:///system/b2g/distribution/bundles/libqc_b2g_ril/chrome.manifest" line: 2}]
E/GeckoConsole(  308): [JavaScript Warning: "Could not map contract ID '@mozilla.org/telephony/telephonyprovider;1' to CID {7292B38A-1950-11E3-9E4A-46906188709B} because no implementation of the CID is registered." {file: "file:///system/b2g/distribution/bundles/libqc_b2g_ril/chrome.manifest" line: 3}]

Not sure if these JavaScript warnings should show up, so setting needinfo? from Tim, the Firefox OS System module owner.

The offending code is in chrome JavaScript, not System app.

Gary, that's because we can't load the binary xpcom RIL & geolocation components since they are compiled for a different gecko version. Not much we can do there.

OK, resolving WONTFIX then, since this is not likely to be fixed. Thanks!
