IllegalArgumentException when using Java 16 and higher

See original GitHub issue

The library currently cannot be used with Java 16.

When running the ClientOfMutabilityDetector tests with Java 16 (library built locally with 1.8), it produces the following results:

Tests run: 172, Failures: 0, Errors: 26, Skipped: 1

One of the failures includes this message:

Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 60

This is the build environment I used to reproduce the issue:

; mvn --version
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: /usr/local/Cellar/maven/3.8.1/libexec
Java version: 16.0.1, vendor: AdoptOpenJDK, runtime: /Library/Java/JavaVirtualMachines/adoptopenjdk-16.jdk/Contents/Home
Default locale: en_GB, platform encoding: UTF-8
OS name: "mac os x", version: "11.3", arch: "x86_64", family: "mac"

In addition, when building MutabilityDetector with Java 16, it produces the following test results:

Tests run: 371, Failures: 0, Errors: 77, Skipped: 5

Again, one of the test failures includes the message:

Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 60

Apologies, I missed the notification of this. I aim to cut a new release soon (most likely using your PR).
