Title:
  Java method getEntry  in class ZipFile  calls a native method which
  return null (it should not since Jar file contains the entry !)

Status in openjdk-6 package in Ubuntu:
  Invalid

Bug description:
  There is a problem with the Java native method:

  private static native long getEntry(long jzfile, String name,
                                          boolean addSlash);

  it returns null although I pass name of a class file which I know for
  sure is located in the Jar file (the ZipFile).

  
  This native method is called from the method :  public ZipEntry getEntry(String name)
  which is in the class   java.util.zip.ZipFile;

  This method looks like:

   /**
       * Returns the zip file entry for the specified name, or null
       * if not found.
       *
       * @param name the name of the entry
       * @return the zip file entry, or null if not found
       * @throws IllegalStateException if the zip file has been closed
       */
      public ZipEntry getEntry(String name) {
          if (name == null) {
              throw new NullPointerException("name");
          }
          long jzentry = 0;
          synchronized (this) {
              ensureOpen();
              jzentry = getEntry(jzfile, name, true);
              if (jzentry != 0) {
                  ZipEntry ze = new ZipEntry(name, jzentry);
                  freeEntry(jzfile, jzentry);
                  return ze;
              }
          }
          return null;
      }


  
  I tried different jdks but all have this problem:

  1.   java-6-openjdk
  2.   jdk1.6.0_26
  3.  j2sdk1.4.1_07

  I believe that since this is a native problem then it must be an
  Ubuntu problem and not java's "fault"

  Please advise:

  thanks
