Motivation:
When BlockHound is installed,
ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify
is reported as blocking call.
Modifications:
Add allowBlockingCallsInside configuration for
ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify
Result:
Fixes#10384
Motivation:
JDK 14 was released and need some special settings to be able to build with. Also there seems to be one regression that we need to workaround for now.
Modifications:
- Add maven profile for JDK 14
- Update blockhound version to be able to work on JDK 14
- Add workaround for possible JDK 14 regression
Result:
Be able to build on JDK 14
Motivation:
JDK is the default SSL provider and internally uses blocking IO operations.
Modifications:
Add allowBlockingCallsInside configuration for SslHandler runAllDelegate function.
Result:
When BlockHound is installed, SSL works out of the box with the default SSL provider.

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).
