Description Sven Efftinge

Given the following file:
"""
import java.util.Collections

class X {
 
  def foo() {
    // some comment
    Collections::<String>emptyList
  }

}
"""

The import is wrongly marked as being unused.

Maybe this helps the investigation: changing to 

  def foo() {
    // some comment
    Collections::<String>emptyList
    Collections::<String>emptyList // or any other call on Collections
  }

makes the warning go away.

Also, not any static call on a class causes this (but I can't see a pattern).

Please ignore my previous comment, I should read the title of the bug too. Since the presence of the comment triggers this, it's also explaining the other cases...
