Bug in ZippedJarVisitor?

Hi!

As far as I can see, there seems to be some bug in ZippedJarVisitor in the distributed version of hibernate-entitymanager.jar beta2:
The extraction of the jarFileName in the constructor does not work under linux. I packaged a .par file inside an .ejb3 file, and when Hibernate tried to "visit" the par,
an exception occurred.

Code:

public ZippedJarVisitor(URL url, boolean detectClasses, boolean detectHbm) { 
      this.detectClasses = detectClasses; 
      this.detectHbm = detectHbm; 
      String file = url.getFile(); 
      jarFileName = file.substring( "file:/".length(), file.length() - "!/META-INF/persistence.xml".length() ); 
      unqualify(); 
   }

"url" has as value something like "file:/home/...", so the created substring has no leading slash. On Windows, this is fine, but on linux this is interpreted as a relative path, causing the following exception:

Code:

java.util.zip.ZipException: No such file or directory
        at java.util.zip.ZipFile.open(Native Method)
        at java.util.zip.ZipFile.<init>(ZipFile.java:204)
        at java.util.jar.JarFile.<init>(JarFile.java:132)
        at java.util.jar.JarFile.<init>(JarFile.java:70)
        ...

I got this Exception with JBoss-4.0.2 in combination with JBoss EJB3 RC1, Java 1.5.0_04 and Suse 9.3, and when I patched the above to

jarFileName = file.substring( "file:".length(), file.length() - "!/META-INF/persistence.xml".length() );

the bug was gone, but this solution wouldn't work on Windows anymore. Is this a bug, or is there some incompatibility that might be responsible for that behaviour?

Thanks,
Stephan

This should be fixed for the next release
