TimeExpressionExtractorFactory.isDefaultExtractorPresent() check if the class for the default time expression extractor is present (i.e. edu.stanford.nlp.time.TimeExpressionExtractorImpl which is in the CoreNLP jar and thus likely always present). It doesn't check though if the resources required by this extractor are present (in the "models" jar which may actually not be present).
When not having the models jar on the classpath and using alternative means of providing the NERClassifierCombiner with models then causes the auto-detection to fail with this exception:

如果相关的话，你最近的邮件看起来像这样：
