I made a zip file which contained .java files rather than .class files; this is not something that one is supposed to do. When I compiled a class against this zip file, I got the message:

I/O exception
1 error

It seems to me that the compiler should give a more meaningful error message when encountering a confusing zip file.

Here is a session which has enough information to reproduce the bug:

219%> m one/two/*.java one/three/*.java
::::::::::::::
one/two/Two.java
::::::::::::::
package one.two;
 
public class Two {
        public int x = 20;
}
::::::::::::::
one/three/Three.java
::::::::::::::
package one.three;
 
public class Three {
        public int y = 40;
}
220%> zip -0 out.zip one/two/*.java one/three/*.java
  adding: one/two/Two.java (stored 0%)
  adding: one/three/Three.java (stored 0%)
invisible:~/bugtest/bold/ziptest 221%> m frog.java
import one.two.*;
 
public class frog {
        frog() {
                int z = new Two().x;
                System.out.println(z);
        }
        public static void main(String[] args) {
                new frog();
        }
}
 
222%> javac frog.java -classpath one.zip:<regularClassPath>
I/O exception
1 error

In JDK 1.3 and JDK 1.2, a spurious error is generated when compiling source
files from a .jar file. Undoubtedly, the problem with .zip files and .jar
files is related, if not identical. See 4232697.

I am doing a compilation for which some of the source files are archived in a
jar file. I compile with "javac -sourcepath files.jar". If none of the files
contain public classes, compilation succeeds. Othewise, I get an error message
complaining that the name of the file is wrong.

(1) Create two files. One is "foo.java":
*/
public class foo {
  public static void main (String[] args) {
    new bar();
  }
}

/*
the other is "bar.java":
*/

public class bar {
}


(2) Compile with javac, and all is well:

javac foo.java


(3) Put bar.java into a jar file and delete bar.java.

jar -cf bar.jar bar.java

(4) Delete all .class files

(5) and try compiling again, this time using a sourcepath option.

javac -sourcepath bar.jar foo.java

This error message appears:

bar.jar(bar.java):1: class bar is public, should be declared in a file named
bar.java
(source unavailable)
1 error
