java.lang.NullPointerException: in == null

Using Jsoup 1.8.3 in my Android app which is now targetting SDK 23 (Marshmallow) and am seeing frequent crashes when trying to get the Document as follows:

Jsoup.connect(link).get()

The stack is as follows:

So I fixed this locally by putting the Jsoup source locally in my project and moving the two .properties files to my “resources” folder and changing line 235 of Entities to InputStream in = Entities.class.getClassLoader().getResourceAsStream(filename); instead of InputStream in = Entities.class.getResourceAsStream(filename);

Since 1.11.1 with this change #959, entities are loaded from data embedded in a class, not a property file, so we shouldn’t get hit by this Android bug any more.
