really good project, and I found some violaitons of your project that may cause a problem, you can take a look if you have free time QWQ 1.bug detect by checkstyle [WARN] \CrawlerPack\src\main\java\com\github\abola\crawler\CrawlerPack.java:94: At-clause should have a non-empty description.

[MissingJavadocType] the above violations are all same type, mission the javadoc or part of it reason to solve them: it will help others to understand your code more easier and it is really easy to fix

line158 CrawlerPack.java Return an empty array instead of null. line94 XTrustProvider.java Return an empty array instead of null. reason to fix above violations: these do not cause fail,but when product the project in the future, this is easy to cause a NullPointerException, so if you have free time, change it to new collection() well be much better
