Method sun.nio.ch.DirectBuffer.cleaner() does not take any parameters in Java 8, code https://github.com/mongodb/mongo-java-driver/blob/master/driver-core/src/main/com/mongodb/internal/connection/tlschannel/util/DirectBufferDeallocator.java#L54 passes null array as a paramter to this method. This leads to NullPointerException when building native image with GraalVM (see below for stacktrace).

Steps to reproduce error:

Unable to find source-code formatter for language: shell. Available languages are: actionscript, ada, applescript, bash, c, c#, c++, cpp, css, erlang, go, groovy, haskell, html, java, javascript, js, json, lua, none, nyan, objc, perl, php, python, r, rainbow, ruby, scala, sh, sql, swift, visualbasic, xml, yaml
