      Description

        After JDK-8251329, we see javac errors with messages like this:
         

        Hello.java:1: error: cannot access unnamed package
        import java.util.Date;
        ^
        ZIP file can't be opened as a file system because an entry has a '.' or '..' element in its name
        1 error

         
        The error is caused by some now invalid jar file (due to . or .. in entry names) which does not necessarily have to do with the compilation unit on which the error is thrown. The error message does not give a clue which jar file is causing the problem. This can be improved to something like:


        Hello.java:1: error: cannot access unnamed package
        import java.util.Date;
        ^
        ZipException opening "invalid.jar": ZIP file can't be opened as a file system because an entry has a '.' or '..' element in its name
        1 error

        To recreate, I have attached a little Java program "GenerateInvalidJar" that generates an invalid jar named invalid.jar which is attached as binary, too. Then, you can call javac -cp invalid.jar Hello.java to provoke the error.
