Tika detects short Japanese sentences as Chinese

[Artur Rashitov]

Given the following code:

val japanese = "私はガラスを食べられます。それは私を傷つけません。"
LanguageDetector.getDefaultLanguageDetector.loadModels().detectAll(japanese)

it produces [zh-CN: MEDIUM (0.579961), zh-TW: MEDIUM (0.405015)]
And the same thing for many short Japanese sentences.
