Motivation:
In #10630, field substitutions were introduced for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST fields. They were required to allow a native image be built with most of Netty (including NetUtil) initialized at build time.
The substitutions created in #10630 only define getters, so the 3 fields can only be read in a native image.
But when NetUtil is initialized at run-time (this is what happens in #10797), its static initialization block is executed, and this block writes to all 3 fields. As the substitutions do not provide any setters, field stores are not valid, and such builds fail.
Modifications:
- Add netty-testsuite-native-image-client-runtime-init Maven module that builds a native image deferring NetUtil class initialization till run-time; this module is used to demonstrate the problem and verify the problem is gone with the fix
- Add no-op setters to substitutions for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST
Result:
A native image initializing NetUtil at run-time builds successfully.
Fixes#10797
Motivation:
https in xmlns URIs does not work and will let the maven release plugin fail:

Modifications:
Use http for xmlns
Result:
Be able to use maven release plugin
Motivation:
We recently released a new netty-build version and changed the artifact name
Modifications:
Update version and artifact name
Result:
Use latest version
Motivation:
JUnit 5 is the new hotness. It's more expressive, extensible, and composable in many ways, and it's better able to run tests in parallel. But most importantly, it's able to directly run JUnit 4 tests.
This means we can update and start using JUnit 5 without touching any of our existing tests.
I'm also introducing a dependency on assertj-core, which is like hamcrest, but arguably has a nicer and more discoverable API.
Modification:
Add the JUnit 5 and assertj-core dependencies, without converting any tests at time time.
Result:
All our tests are now executed through the JUnit 5 Vintage Engine.
Also, the JUnit 5 test APIs are available, and any JUnit 5 tests that are added from now on will also be executed.
Motivation:
Conscrypt 2.5.1 is available and it's a good idea to upgrade to the latest version.
Modification:
Upgraded Conscrypt 2.4.0 to 2.5.1
Result:
Newer Conscrypt version.
Motivation:
SLF4J 1.7.30 is the latest version in 1.7.x and we should upgrade to it from 1.7.21.
Modification:
Changed 1.7.21 to 1.7.30
Result:
Newer version of SLF4J
Motivation:
Since GraalVM version 19.3.0, instances of java.net.InetAddress (and its subclasses Inet4Address and Inet6Address) are not allowed in native image heap (that is, they cannot be stored in static fields of classes initialized at build time or be reachable through static fields of such classes). When building a native image, it makes sense to initialize at build time as many classes as possible.
But some fields of some classes in Netty (for example, NetUtil.LOCALHOST4) contain InetAddress instances. If a program is using code path that makes it possible to reach such fields at build time initialization, it becomes impossible to build a native image initializing core Netty classes initialized at runtime. An example of such a program is a client that uses netty-dns.
Modifications:
- Add netty-testsuite-native-image-client Maven module to test that such an example program can be built after the corresponding fixes
- Add native-image.properties to resolver-dns module to move initialization of some classes to runtime (some of them are parsing configuration during initialization, so it makes no sense to initialize them at build time; for others, it's needed to avoid InetAddress reachability at build time)
- Add substitutions for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST to overcome the InetAddress-related prohibition
- Extract some initialization code from NetUtil to NetUtilInitializations to allow it to be used by the substitutions
Result:
A client program using netty-dns with --initialize-at-build-time=io.netty builds successfully
Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
Java 16 will come around eventually anyway, and this makes it easier for people to experiment with Early Access builds.
Modification:
Added Maven profiles for JDK 16 to relevant pom files.
Result:
Netty now builds on JDK 16 pre-releases (provided they've not broken compatibility in some way).
Bumps ant from 1.9.7 to 1.9.15.

Motivation:
Avoid keeping unused dependencies around.
Modification:
Remove all references to javassist dependency, since it does not appear to be used by anything.
Result:
One less dependency to worry about.
Motivation:
To reduce latency and RTTs we should use TLS False Start when jdkCompatibilityMode is not required and its supported
Modifications:
Use SSL_MODE_ENABLE_FALSE_START when jdkCompatibilityMode is false
Result:
Less RTTs and so lower latency when TLS False Start is supported
Motivation:
AlgorithmId.sha256WithRSAEncryption_oid was removed in JDK15 and later so we should not depend on it as otherwise we will see compilation errors
Modifications:
Replace AlgorithmId.sha256WithRSAEncryption_oid usage with specify the OID directly
Result:
Compiles on JDK15+
Motivation:
JCTools 3.1.0 is out and includes several fixes, see https://github.com/JCTools/JCTools/releases/tag/v3.1.0
Modification:
Upgrade jctools-core version in pom.xml
Result:
Netty ships latest version of jctools.
Motivation:
There was a new netty-tcnative release which we should use. Beside this the SSLErrorTest was quite fragile and so should be adjusted.
Modifications:
Update netty-tcnative and adjust test
Result:
Use latest netty-tcnative release
Motivation:
We are far behind with the version of Conscrypt we are using during testing. We should ensure we use the latest.
Modifications:
- Update conscrypt dependency
- Ensure we use conscrypt provider in tests
- Add workarounds for conscrypt bugs in testsuite
Result:
Use latest Conscrypt release
Motivation:
We need to make some slightly changes to be able to build on Java15 as some previous deprecated methods now throw UnsupportedOperationException
Modifications:
- Add code to handle UnsupportedOperationException
- Revert previous applied workaround for bug that was fixed in Java15
- Add maven profile
Result:
Be able to build with latest Java15 EA release
Motivation:
ALPN support was backported to java 8 lately. Ensure we support it if the user uses the latest java 8 release
Modifications:
- Update logic to be able to detect if ALPN is supported out of the box when using Java8
- Update jetty alpn version
Result:
Be able to use ALPN out of the box when using java 8u251
Motivation:
We should update our optional bouncycastle dependency to ensure we use the latest which has all the security fixes
Modifications:
Update bouncycastle version
Result:
Fixes https://github.com/netty/netty/issues/10184
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:
A new netty-tcnative version was just released which fixes a small memory leak.
Modifications:
Update to 2.0.30.Final
Result:
Small memory leak fixed
Motivation:
Sometimes it is useful to do something depending on the Ssl ClientHello (like for example select a SslContext to use). At the moment we only allow to hook into the SNI extension but this is not enough.
Modifications:
Add SslClientHelloHandler which allows to hook into ClientHello messages. This class is now also the super class of AbstractSniHandler
Result:
More flexible processing of SSL handshakes
