I applied TestsShouldNotBePublic to JabRef's code.

I get compile errors afterwards:

/home/runner/work/jabref/jabref/src/test/java/org/jabref/logic/bst/BstFunctionsTest.java:7: error: BstCaseChangersTest is not public in org.jabref.logic.bst.util; cannot be accessed from outside package
import org.jabref.logic.bst.util.BstCaseChangersTest;

I know, this is bad software design. However, I think, rewriting should not introduce compile errors.
