Summary: Crash when using a iOS Cordova plugin within a WebSocket
event
Key: CB-9102
URL: https://issues.apache.org/jira/browse/CB-9102
Project: Apache Cordova
Issue Type: Bug
Components: iOS
Affects Versions: 3.8.0
Reporter: Iñaki Baz Castillo
I've coded a cordova plugin for iOS. It is exported as a JavaScript object with
multiple functions in `window.cordova.plugins.iosrtc`.
If I use any of those exported functions within the callback of a WebSocket
event (onopen, onmessage, etc), the plugin/app usually crashes:

--------------------------------
IMPORTANT: If I run a setTimeout within the WebSocket event and run the plugin
function inside it, the app DOES NOT crash.
It may be related to https://issues.apache.org/jira/browse/CB-2301
NOTE: This issue is NOT about sleep/resume at all as it happens immediately
when I open the app and a WebSocket connects.
