import static java.lang.Math.PI;

public class Foo {}

gives a warning, that the static import is never used (OK). If you declare a PI,
the warning disappears (not OK):

import static java.lang.Math.PI;

public class Foo {
  boolean PI;
}

It seems that it does not matter where such a variable is declared in the
compilation unit the warning always disappears.

Note: you can use PI from Math in a different scope (OK):

import static java.lang.Math.PI;

public class Foo {
  double d = PI; // from Math

  void f() {
    boolean PI;
  }
}

class Bla {
  double d = PI; // from Math
}
