Motivation:
JDK15 is about to be released as GA, we should ensure netty works and builds on it. SSLSession#getPeerCertificateChain() throws UnsupportedOperationException in JDK15 and later as it was deprecated before and people should use SSLSession#getPeerCertificates(). We need to account for that in our tests
Modifications:
- Catch UnsupportedOperationException in our testsuite and ignore it when on JDK15+ while rethrowing it otherwise.
Result:
Testsuite passes on JDK15+
