alpn-boot jar causing conflict with jdbc (Oracle) connection

[nkmittal]

I am using a Docker environment to build my Play 2.5.x (Scala 2.11.11) server where from the server I connect to AWS RDS Oracle instance Version 12.1.0.1. When I add alpn-boot (alpn-boot-8.1.13.v20181017.jar) jar to Java boot classpath (required by apns-http2) I observe that sometimes my server can't connect to RDS instance. It does not happen always but happens intermittently. I am using "ojdbc7.jar" for Oracle JDBC driver. ‘alpn’ stands for Application Layer Protocol negotiation and this jar is needed for connecting as client over HTTP/2 to a remote server (Refer: http://www.eclipse.org/jetty/documentation/current/alpn-chapter.html).
I use JVM option "-J-Xbootclasspath/p:lib/alpn-boot-8.1.13.v20181017.jar" to add the jar to boot classpath.
Has anyone observed such kind of issue ?
