A recent version of IntelliJ (16+ EAP) started automatic Java static imports.
To be clear: I am OK with non-static imports.
Can I disable only static imports?
There are checkboxes for controlling automatic importing at File | Settings | Editor | General | Auto Import. Now there's only one, but in the next EAP, there will be separate ones for class and method/field imports.
After IDEA 2016.2.1, it's controlled by
Show import suggestions for static methods and field checkbox.
