Java Swing Graphics2D drawString slow init?

I came across a very strange behavior of Java Graphics2D draw String.

If I give a font name like

Font f = new Font("Helvetica", Font.PLAIN, 10);

Then, on the device’s screen, the first call to g2D.drawString can take up to 600 ms. This creates a screen jam, it is not important, but rather annoying.

Switching the font name to the default values, such as "Monospace", will solve the problem.

Has anyone encountered similar problems?
