Senduran commented on SYNAPSE-1014:
-----------------------------------
Since the exception is thrown at http nio level, I tried upgrading the http
core version to 4.3.3 and http client to 4.3.6. (current versions 4.3, 4.3.1)
This upgrade reduces the exception occurrence but didn't completely eliminates.
Couldn't upgrade to a higher version due to test case failures.
