> Many methods in {{ByteBuffer}} now return an instance of {{ByteBuffer}} instead of {{Buffer}}. This results in {{NoSuchMethodError}} when code compiled in Java 9 is executed in an older JVM. See [this|https://jira.mongodb.org/browse/JAVA-2559] and [this|https://github.com/plasma-umass/doppio/issues/497#issuecomment-334740243] for reference and proposed fixes.
