Now i remember why this check isn't enabled. it is exactly as the comment
states, some real work. The first error you see from the check against `main`
is promising:
```
> Task :lucene:core:compileJava
/home/rmuir/workspace/lucene/lucene/core/src/java/org/apache/lucene/index/TermsEnum.java:200:
error: [ClassInitializationDeadlock] Possible class initialization deadlock:
BaseTermsEnum is a subclass of the containing class TermsEnum
new BaseTermsEnum() {
^
(see https://errorprone.info/bugpattern/ClassInitializationDeadlock)
```
Unfortunately, there are 82 errors in `lucene-core` alone. Here's a
condensed version:
```
