I can confirm this bug as of cb0e38f in the develop branch.

The dataset is created but there is no thumbnail for a jpg file and I'm seeing "Internal Server Error" when I click Download, as shown in the screenshot below. In server.log, on clicking Download, the error says java.io.IOException: Failed to open local file file:///Users/pdurbin/dataverse/files/10.5072/FK2/I9O8AB/15c5ead307a-a2619b2c5d5d.

On create, the directory where files are to be stored is not created. In production the directory is something like /usr/local/glassfish4/glassfish/domains/domain1/files/10.5072/FK2/IF3GJB.

The reason the directory is not being created is that this.getIdentifier() is null in the getFileSystemDirectory method of Dataset.java.

Here's how the method looks as of cb0e38f:

    public Path getFileSystemDirectory() {
        Path studyDir = null;

        String filesRootDirectory = System.getProperty("dataverse.files.directory");
        if (filesRootDirectory == null || filesRootDirectory.equals("")) {
            filesRootDirectory = "/tmp/files";
        }

        if (this.getAuthority() != null && this.getIdentifier() != null) {
            studyDir = Paths.get(filesRootDirectory, this.getAuthority(), this.getIdentifier());
        }

        return studyDir;
    }

Here's a link to the code:

I just created pull request #3868 and will move this issue to code review at https://waffle.io/IQSS/dataverse

@raprasad - you mentioned in standup you were going to take a look at this.

@djbrooke I just looked at it. It looks good. Moving to QA
