Question

在我的Sinatra应用程序中，我正在使用宝石'sinatra-initializers'，'sinatra / asset_pipeline'，'sinatra / assetpack'等等，我有一个初始化程序，可以加载自然语言处理库：

#00_initializer.rb
    StanfordCoreNLP.jar_path = '/path/to/stanford-core-folder/'
    StanfordCoreNLP.model_path = '/path/to/stanford-core-folder/'
    NLPPipeline = StanfordCoreNLP.load(:tokenize, :ssplit, :pos, :lemma, :parse)

#nlp.rb
    def get_tokens(word)
        text = StanfordCoreNLP::Annotation.new(word)
        NLPPipeline.annotate(text)
        text.get(:tokens).each {|token| p token.get(:value).to_s} 
    end

当我启动服务器时，一切正常：

  >> $ rackup
Adding annotator tokenize
Adding annotator ssplit
Adding annotator pos
Loading default properties from tagger /Users/JW/Dropbox/Dev/Websites/FrontEnd/_JS plugins/stanford-core-nlp-minimal/taggers/english-left3words-distsim.tagger
Reading POS tagger model from /Users/JW/Dropbox/Dev/Websites/FrontEnd/_JS plugins/stanford-core-nlp-minimal/taggers/english-left3words-distsim.tagger ... done [1.5 sec].
Adding annotator lemma
Adding annotator parse

但是一旦我调用该函数，我就会得到一个

RuntimeError at /
java.lang.NullPointerException

直到昨天，一切都很好，据我所知，我没有改变任何东西。试图挖掘周围的问题，我从初始化程序中注释掉了所有内容。但是，初始化程序加载与以前完全相同：

>> $ rackup
    Adding annotator tokenize
    Adding annotator ssplit
    Adding annotator pos
    Loading default properties from tagger /Users/JW/Dropbox/Dev/Websites/FrontEnd/_JS plugins/stanford-core-nlp-minimal/taggers/english-left3words-distsim.tagger
    ...[etc]

    [2015-08-02 19:30:57] INFO  WEBrick::HTTPServer#start: pid=26229 port=9292

所以...我的问题：幻影初始化器的处理是什么？而且，我突然行为不端的Java库可能是什么原因？

为什么删除初始化程序不会改变行为？
