Hang in setUpBeforeClass. Master will not initialize. Root cause is a NoSuchMethodError.

This is a known issue with ByteBuffer in JDK 8 vs ByteBuffer in later versions. When code is compiled with Java 9 or later using a specific subset of ByteBuffer APIs, the resulting bytecode will not link with Java 8's runtime. 

protobuf included into hbase-thirdparty was likely compiled with Java 9 or later. We shade that bytecode as is into hbase-thirdparty.  Tests were attempted with Java 8, so this failure case manifested.

Apache Maven 3.8.3 (ff8e977a158738155dc465c6a97ffaf31982d739)
Java version: 1.8.0_312, vendor: Azul Systems, Inc., runtime: /Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/jre
OS name: "mac os x", version: "12.0.1", arch: "aarch64", family: "mac"

We should be able to fix this problem by compiling protobuf with Java 8 and then shading the result when building hbase-thirdparty.
