Is it necessary to call a public non-final method from a constructor? This can cause issues when somebody subclasses IcuTokenizerFactory as initialization order gets important. I'd opt for making #getIcuConfig() private which avoids the issue. Alternatives: Declare #getIcuConfig() or the class as final.

@xuzha: Sorry that it took so long that somebody reviews your PR. I left a few comments. Just let me know if you have further questions. I think it would make sense to resolve conflicts first given that this branch is now quite out of date. |

Thx @danielmitterdorfer for the review. |
|
ping @xuzha, I think this needs updating and then another review by @danielmitterdorfer ? |
|
Sorry @dakrone, I was sick last week. I will try to update this ASAP. |

Thanks @danielmitterdorfer for the review. I just pushed another commit to address the comments. Sorry that it took a while to update this, it looks so hacky to me :-) |
|
@xuzha I answered your questions. I hope that helps now. |

Thanks @danielmitterdorfer, I just pushed another commit. |

Nit: you could use Collections.emptyList() instead of new ArrayList<>()
