DigitalPersona U.are.U java SDK doesnt answer without GUI

I'm currently developping a JAVA program which uses Digital Persona 4500.[DigitalPersonaBiometricSDKforWindows_3.4.0]

We're facing problems with it, the sample code uses a GUI that you can sample digital, it works fine with the GUI.

But if we dont use the GUI, the code stops on Reader.Capture()... I've tried many things like another Thread only for sampling and etc.

ReaderCollection m_coll = UareUGlobal.GetReaderCollection();
m_coll.GetReaders();
Reader m_reader = m_coll.get(0);
m_reader.Open(Reader.Priority.COOPERATIVE);
Reader.CaptureResult cr = m_reader.Capture(Fid.Format.ANSI_381_2004, Reader.ImageProcessing.IMG_PROC_DEFAULT, m_reader.GetCapabilities().resolutions[0], -1);
System.out.println(cr.quality);

I have just added solution in below question,

Call to Reader.Capture() in DigitalPersona U.are.U SDK does not return

Copying same answer here,

I faced the similar issue and it can be fixed by opening a reader in exclusive mode as below,

m_reader.Open(Reader.Priority.EXCLUSIVE);

Refer to below lines from documents,

public static final Reader.Priority COOPERATIVE

Client uses this priority to open reader in cooperative mode. Multiple clients with this priority are allowed. Client receives captured images if it has window with focus.

public static final Reader.Priority EXCLUSIVE

Client uses this priority to open reader exclusively. Only one client with this priority is allowed.
