Java Google Drive SDK SocketTimeoutException on File.insert.execute

问题

I have been using the Google Drive SDK in both Java and Objective-c for months now and suddenly today (Jul 10, 2013) inserting new files using the java api (google-api-client-1.15.0-rc.jar & version 1.14) is failing to execute on FileInsert.execute(). Here is the static helper method I've been using (basically a copy from the DrEdit tutorials):

    public static File insertFile(Drive driveService, String title, String description,
            String parentId, String mimeType, java.io.File content) {
        System.out.println("<GDrive insertFile> start");
        File body = new File();
        body.setTitle(title);
        body.setDescription(description);
        body.setMimeType(mimeType);

        if (parentId != null && parentId.length() > 0) {
            body.setParents( Arrays.asList(new ParentReference().setId(parentId)) );
        }
        Insert fileInsert = null;
        System.out.println("<GDrive insertFile> before content attache");
        if (content != null && content.length() > 0) {
            FileContent mediaContent = new FileContent(mimeType, content);
            try { fileInsert = driveService.files().insert(body, mediaContent); }
            catch (IOException e) { e.printStackTrace(); }
        } else {
            try { fileInsert = driveService.files().insert(body); }
            catch (IOException e) { e.printStackTrace(); }
        }

        try {
            if (fileInsert != null) {
                System.out.println("<GDrive insertFile> before execute");
                File file = fileInsert.execute();
                System.out.println("<GDrive insertFile> file posted " + file.getId());
                return file;
            } else return null;
        } catch (IOException e) {
            System.out.println("An error occured: " + e);
            return null;
        }
    }

Obviously System.out was used to locate the issue, it hangs up on "before execute". I haven't been able to find any posts about Google server issues or changes in how the api is to be used. Here is the error message that is logged when the app fails any time after 20 - 180 seconds:

An error occured: java.net.SocketTimeoutException: Read timed out
Exception in thread "main" java.lang.NullPointerException

Thanks.
