With the same code to upload file to google drive, linux and windows work well. but it does not work in aix.

It hangs in “update.execute();”

void upload(AbstractInputStreamContent content, String driveFile, boolean replaceFile) {
    // First try to see if the metadata for the file already exists.  If so,
    // update it.
    File file = findMatchingFile(driveFile);
    if (file != null) {  
        if (replaceFile) {
            try {
                // update content
                File newMetadata = new File();
                newMetadata.setName(file.getName());
                newMetadata.setParents(file.getParents());
                Drive.Files files = service.files();
                Update update = files.update(file.getId(), newMetadata, content);
                update.execute();

Can you give me some ideas on it?

Thank you.

It does not fix the issue.
