IDEA thinks that the al parameter is used somehow in new al()
(Test.f() method). As a result "import foo2.*;" is marked as
redundant (this is wrong). If you rename the parameter to "a"
(now it's correct, "Parameter a is never used").
If you comment out "import foo2.*" nothings is marked (wrong).
If you now rename the parameter to "a", IDEA will say as expected
"Cannot resolve symbol al" and "Parameter a is never used".

// foo1/Test.java
package foo1;
import java.util.ArrayList;
import foo2.*;
public class Test {
private static void f(ArrayList al) {
System.out.println("val="+new al());
}
public static void main(String[] args) {
f(new ArrayList());
}
}
===============================================
// foo2/al.java
package foo2;
public class al {
public String toString() {
return "foo2.al";
}
}
