Motivation:
As we have java8 as a minimum target we can use MethodHandles. We should do so when we expect to have a method called multiple times.
Modifications:
- Replace usage of reflection with MethodHandles where it makes sense
- Remove some code which was there to support java < 8
Result:
Faster code
Motivation:
We can use lambdas now as we use Java8.
Modification:
use lambda function for all package, #8751 only migrate transport package.
Result:
Code cleanup.
Motivation:
CleanerJava9 currently fails whever a SecurityManager is installed. We should make use of AccessController.doPrivileged(...) so the user can give it the correct rights.
Modifications:
Use doPrivileged(...) when needed.
Result:
Fixes https://github.com/netty/netty/issues/8201.
Motivation:
Java9 adds a new method to Unsafe which allows to free direct ByteBuffer via the cleaner without the need to use an commandline arguments.
Modifications:
- Add Cleaner interface
- Add CleanerJava9 which will be used when using Java9+ and take care of release direct ByteBuffer
- Let Cleaner0 implement Cleaner
Result:
Be able to free direct ByteBuffer on Java9+ again without any commandline arguments.
