Subject [VFS2] I can't delete a file with VFS2 if it's pointed by two variables
Date Mon, 24 Sep 2012 09:09:00 GMT
This is the code:

    FileObject localRecipients = null;
    FileObject localRecipientsCsv = null;

    try {
        if (dto.getCsvFile() != null) {

        // file sul server remote csv o zip
        FileObject remoteRecipientsFile = manager.resolveFile(
            semaphoreFile.getParent(), dto.getCsvFile());

        // carico nel localRecipients il file specificando un nuovo
        // nome
        localRecipients = manager.resolveFile(Functions
            .buildLocalRecipientsfilename(configurationHeader,
                remoteRecipientsFile));

        localRecipients.copyFrom(remoteRecipientsFile,
            Selectors.SELECT_SELF);

        // controllo se รจ presente l'estensione zip sul file remoto.
        if (remoteRecipientsFile.getName().getExtension()
            .equalsIgnoreCase(Constants.EXTENSION_ZIP.getValue())) {

        // this builds something like zip:// arch-file-uri[! absolute-path]
            FileObject localRecipientsZip = manager
                .resolveFile(Functions
                    .buildCompressedFileRoot(localRecipients));

            localRecipientsCsv = VFS.getManager().resolveFile(
                localRecipients.getParent(),
                localRecipients
                    .getName()
                    .getBaseName()
                    .substring(
                        0,
                        localRecipients.getName()
                            .getBaseName().length()
                            - Constants.EXTENSION_ZIP
                                .getValue()
                                .length() - 1));
            localRecipientsCsv.copyFrom(
                localRecipientsZip.getChildren()[0],
                Selectors.SELECT_SELF);

            localRecipientsZip.close();
            remoteRecipientsFile.close();
            remoteRecipientsFile = null;
            localRecipientsZip = null;
        } else {
            localRecipientsCsv = localRecipients;
        }

    /*   */

        } else if (dto.isXMLRecipients()) {
        /* */

        }
    } catch (FileSystemException e) {
        /***/
    }

    try {
        notifyObservers(new XMLDLoggerTrigger(
            DeliveryStatusType.RECIPIENTS_UPLOAD_STARTED, new Object[] {
                this.id, new Date(),
                localRecipients.getName().getBaseName() }));

        reader.attach(this);
        reader.load();

    } catch (IOException e) {
        /* */
    } finally {
        try {
        notifyObservers(new XMLDLoggerTrigger(
            DeliveryStatusType.RECIPIENTS_UPLOAD_FINISHED,
            new Object[] { this.id, new Date(), recipientsCount }));

        if (localRecipientsCsv != null) {
            localRecipientsCsv.delete();
            localRecipientsCsv.close();
            localRecipientsCsv = null;
        }

        if (localRecipients != null) {
            localRecipients.getContent().close();
            // ERROR
            localRecipients.delete();
            localRecipients.close();
            localRecipients = null;
        }

        } catch (FileSystemException e) {
        saveStep(DeliveryStatusType.GENERIC_ERROR,
            "xmld2.systemlogger.error.filesystemexception", e);
        }
    }

    /*  */

}

The problem is localRecipients.delete(); where I have an error about it's
not possible to delete a file. And I also can't delete it from the
filebrowser because someone is reading it. The problem is happening when I
go inside the
if (remoteRecipientsFile.getName().getExtension()
.equalsIgnoreCase(Constants.EXTENSION_ZIP.getValue())) {

branch because localRecipients and localRecipientsZip are pointing to the
same file. But I close localRecipientsZip.

It's something stupid but I can't see it.
