Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Android users who are getting                                *
  * ConcurrentModificationException when using Cordova plugins.  *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * Cordova application will sometimes crash with                *
  * ConcurrentModificationException on start up. Plugins execute *
  * on a non-UI thread by default, and if a plugin calls         *
  * "getPlugin()" while the UI thread is dispatching an          *
  * onMessage (or one of the various other plugin functions) the *
  * application will crash because of the race condition.        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *
