java.util.zip.ZipFile.ZipFile(String),
java.util.jar.JarFile.JarFile(String name) and
java.util.jar.JarFile.JarFile(String name, boolean verify)
cause core dump in JDK-1.2-V when called
with name = null.

An example to reproduce this:
===== Test15.java ====
import java.util.zip.*;
import java.io.File;

public class Test15 {

  public static void main (String argv[]) {

    File file = null;
    String fileName = null;

    try {
        new ZipFile(fileName);
    }
    catch (NullPointerException npe) {
        System.out.println("Passed");
        return; }
    catch (Throwable e) {
        System.out.println("Failed: NullPointerException expected");
        return;
    }
    System.out.println("Failed: NullPointerException expected");
    return;
  }

}
