Now catching all Throwable.
This is more aggressive than the previous behavior of catching all Exception.
We made this change to greatly reduce the chances of any Error, such as
OutOfMemoryError, being silently lost.
Exceptions thrown from on* success callbacks will no longer be passed to
onError callbacks.
Improved logging:
No more System.err
Improved and more consistent logging levels
Callback logging
ao-messaging-tcp-1.2.1
Release Notes
Minimum Java version changed from 1.7 to 1.8.
Reduced use of property substitutions in pom.xml.
This is to help 3rd-party parsers that fail to perform full Maven-compatible substitutions.
