Remove excluded cipher suites matching the prefix `SSL` because the names of the
IBM Java 8 JVM cipher suites have the prefix `SSL` while the
`DEFAULT_EXCLUDED_CIPHER_SUITES` of org.eclipse.jetty.util.ssl.SslContextFactory
includes "^SSL_.*$". So all IBM JVM cipher suites are excluded by
SslContextFactory using the `DEFAULT_EXCLUDED_CIPHER_SUITES`.
