Motivation:
Java 13 requires special flags to be set to make BlockHound work
Modifications:
- Added jdk13 profile to `transport-blockhound-tests`
- Enabled `-XX:+AllowRedefinitionToAddDeleteMethods` on jdk13
Result:
The tests work on Java 13
Motivation:
Netty is an asynchronous framework.
If somebody uses a blocking call inside Netty's event loops,
it may lead to a severe performance degradation.
BlockHound is a tool that helps detecting such calls.
Modifications:
This change adds a BlockHound's SPI integration that marks
threads created by Netty (`FastThreadLocalThread`s) as non-blocking.
It also marks some of Netty's internal methods as whitelisted
as they are required to run the event loops.
Result:
When BlockHound is installed, any blocking call inside event loops
is intercepted and reported (by default an error will be thrown).
