Java progressbar color changed

I am applying a JAVA application with Matlab. When I test my program in Eclipse, everything is fine, the progress bar is showing in desired color. But when I call this JAVA application(through jar file) from Matlab. The progress bar is all green, I am struggling in this situation, I do not know where is the problem as everything is fine when I run it without Matlab.

My JAVA color as follows:

JProgressBar progressBarFirstSubjectNeuralSignal;
UIDefaults defaultsFirstSubject = new UIDefaults();

defaultsFirstBar.put("ProgressBar[Enabled].foregroundPainter", new 
CustomPainter(Color.RED));

defaultsFirstBar.put("ProgressBar[Enabled+Finished].foregroundPainter", new 
CustomPainter(Color.RED));

progressBarFirstBarSignal.putClientProperty("Nimbus.Overrides.InheritDefaults", Boolean.TRUE);   
progressBarFirstBarSignal.putClientProperty("Nimbus.Overrides", defaultsFirstSubject);
