Raise the Netty 5 minimum required Java version to Java 11.
Motivation:
Java 11 has been out for some time, and Netty 5 is still some ways out.
There are also many good features in Java 11 that we wish to use, such as VarHandles, var-keyword, and the module system.
There is no reason for Netty 5 to not require Java 11, since Netty 4.x will still be supported for the time being.
Modification:
Remove everything in the pom files related to Java versions older than Java 11.
Remove the animal-sniffer plug-in and rely on the `--release` compiler flag instead.
Remove docker files related to Java versions older than Java 11.
Remove the copied SCTP APIs -- we should test this commit independently on Windows.
Remove the OpenJdkSelfSignedCertGenerator.java file and just always use Bouncy Castle for generating self-signed certificates for testing.
Make netty-testsuite tests pass by including Bouncy Castle as a test dependency, so we're able to generate our self-signed certificate.
Result:
Java 11 is now the minimum required Java version.
Motivation:
`transport-native-epoll` doesn't have ARM release package.
Modification:
This PR added cross compile profile for epoll. Then we can easily build aarch64 package on X86 machine.
Result:
Fixes#8279
Motivation:
We should use the same java versions whenever we use CentOS 6 or 7 and also use the latest Java12 version
Modifications:
- Use same Java versions
- Use latest Java 12 version
- Remove old configs which are not used anymore
Result:
Docker cleanup
motivation: setup for testing across different permutations of linux and java versions
changes:
* refactor docker file to allow dynamic versions of centos and java
* add docker compose driver files for centos 6, 7 and java 1.8, 1.9, 1.10, 1.11
* update instructions
Motivation:
It would be good to provide a docker image for people that want to build netty on linux.
Modifications:
Add a docker file
Result:
People can more easily build netty. Fixes [#7585].
