I just updated to 4.2.2 and am running into some issues with code that previously worked. I saw that this was a previous issue that was solved by changing HTTPClient to 4.4.x. I did this and rebuilt my project, but I'm still getting "Needs a boundary value".

The AdminConnection (admin) is fine, my project is actually failing when making a Connection from admin. Here's the code:

    File file = new File(path); 
    Connection conn = null; 

    // Load file and then delete it 
    try {
        FileWriter fw = new FileWriter(file); 
        BufferedWriter bw = new BufferedWriter(fw); 
        bw.write(inputFile); 
        bw.close(); 
        fw.close(); 

        conn = admin.memory(graphTitle).create(file.toPath()).connect(); 
        file.delete(); 

    } catch (StardogException|IOException e) { 

        file.delete(); 
        throw e; 
    }

    return conn;
