Dropbox V2 API Java, Client call on Tomcat fails without any log details

Hi Gregory,

Thanks for the reply.

During testing I've cleared the dropbox account between tests as I did notice that files wouldn't be overwritten, so this isn't the cause of our problem.

During development I ran the code using a unit test. It retrieved the test file from an FTP server changed its name (adding a timestamp to prevent duplicate names) and then uploaded this file to the dropbox account. So far so good.

Once I had completed the development of the required code I performed a test on a locally running tomcat 8 server. This is where the strangeness starts.

The following code simply won't execute properly:

private DbxClientV2 getDropboxClient(String authToken) throws ProcessFailedException{
        log.debug("getDropboxClient");
        
        try{
            //Create the Dropbox connection client
            DbxRequestConfig config = new DbxRequestConfig("xxxxxxxxxxxxx", "nl_NL");            
            DbxClientV2 client = new DbxClientV2(config, passwordEncryptionService.decryptPassword(authToken));
            
            return client;
        } catch (Exception e){
            throw new ProcessFailedException(e);
        }
        
}

The DbxRequestConfig is created but once I try to initialize the DbxClientV2 nothing happens. No exceptions are thrown, no messages are displayed in the log. As far as I can see the call to dropbox isn't ever made.
