      Description

      The issue is that on Windows from the command prompt with Java 10, if you do:

          javac *.java

      in a directory where "*.java" matches nothing, you get a horrible, horrible error message. So bad, it scares people away from Java. IMHO this is bad enough to be considered a bug, and a P3 bug under the old JavaSoft system, at that!

      Here's the inexcusably awful error message:

      C:\Users\nickt\Documents\java_projects\lab-01-ntteng\part1>javac foooo*.java
      Exception in thread "main" java.nio.file.InvalidPathException: Illegal char <*> at index 5: foooo*.java
