java.lang.ExceptionInInitializerError in AutoValueSubclassLeaked caused by NullPointerException in Caffeine

I'm getting the following crash inside error-prone on Java 8. Works fine on Java 11. It's not urgent for me, I'm happy to not support building on Java 8 at this point.



```

     error-prone version: 2.4.0

     BugPattern: AutoValueSubclassLeaked

### To reproduce



Make sure OpenJDK 8 is available in JAVA_HOME, this example assumes it's in `/usr/lib/java-8-openjdk-amd64/`.



```

$ git clone git@github.com:sjamesr/jfreesane.git

$ cd jfreesane

$ git fetch origin pull/102/head

$ git checkout FETCH_HEAD

$ JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/ ./gradlew check

```



### What version of Error Prone are you using?



2.4.0, invoked by net.ltgt.errorprone plugin version 1.3.0.
