Review Comment:
Should avoid static initializer blocks in general... they make for
hard-to-test code, not to mention the potential bootstrapping issue mentioned
here. Should use JUnit `@BeforeAll` annotation to initialize static fields in
test case classes, if possible, to make sure JUnit does the right thing
automatically.
