Please provide any additional information below. Attach a screenshot if possible.

I can reproduce this by creating a hello world with a JTabbedPane. I can, however, force the tab text to black with:

import javax.swing.UIManager;
import java.awt.Color;
UIManager.put("TabbedPane.foreground", new Color(0,0,0));

Or with something like:

JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.TOP);
tabbedPane.setForeground(Color.BLACK);
