Particular values of -fx-border-color may curtain off -fx-border-style

(JavaFX 2.0 bet b35 + JDK 1.6.0_25 + WinXP SP3)

The problem is:

Below works fine as I expected

vbox.setStyle("-fx-border-insets: -10 -20 -20 -10, -30; -fx-border-color: red blue yellow green, blue; -fx-border-style: dotted solid dotted solid, dotted;");

but if I changed it to below(only the colors changed), all the 4 "inner" borders magically become the same dotted

vbox.setStyle("-fx-border-insets: -10 -20 -20 -10, -30; -fx-border-color: blue blue blue blue, yellow; -fx-border-style: dotted solid dotted solid, dotted;");

Complete codes below for re-producing
