Netty 4.2.7 introduced a new leak detection mechanism for tests that is more reliable and has lower overhead. micronaut-projects/micronaut-test#1291 introduces a micronaut-test module that uses this new mechanism. However, the new detector is more strict about resource lifetimes, so tests need various small adjustments: - Contexts must be closed at the end of the test - Event loops must be shut down - Tests must use only threads created in those tests (no Finalizers, no reactive boundedElastic) - SSL contexts must be released immediately There is also one minor leak fix in this PR, related to h2c support, in Http2ServerHandler. Draft because this requires the new micronaut-test module.
