There is a Vocabulary unit test
(https://github.com/apache/incubator-joshua/blob/master/tst/joshua/corpus/VocabularyTest.java)
and a FormatUtil Unit test
(https://github.com/apache/incubator-joshua/blob/master/tst/joshua/util/FormatUtilsTest.java)
These should be updated accordingly. I guess Unit tests are not run
currently during build.
