Java 8
Currently jim-core is compiled for Java 8, and only processes Java 8 files. This will change in the near future.
English
jim-core relies on intt to split identifier names into words and abbreviations. intt uses English dictionaries and assumes English morphology (to an extent). Using jim-core to split names that are not in English may result in some degradation in performance. intt can be configured to use alternative dictionaries, which may help.
