ConcurrentModificationException when playing around with connections #441

saiimons · 2018-06-12T21:46:44Z

Summary

While playing around with connections, I end up having a ConcurrentModificationException.

Library version

1.6.0

Preconditions

Running a scan, monitoring device status.

Steps to reproduce actual result

Connect and disconnect a device, and subscribing to notifications on a specific UUID

Minimum code snippet reproducing the issue

Sorry, can't share for the moment, but if I can set up a limited example, I'll share.

Logs from the application running with setting `RxBleLog.setLogLevel(RxBleLog.VERBOSE)`

Cleaned up the logs from useless/sensitive stuff :

The text was updated successfully, but these errors were encountered:

DisconnectionRouter is storing emitters waiting for information about disconnection in a Queue. This Queue may be accessed concurrently and it was not prepared for this scenario. Additionally there could be a race if an exception would happen when a new emitter would get subscribed. Fixes #441
