FULL PRODUCT VERSION :
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

A DESCRIPTION OF THE PROBLEM :
in method createFontResource line 333:

> if (index == 0 || name.equals(fontname))

name is the parameter to the method.index can be != 0 when loading .ttc file so the check for equality is performed.

createFontResource is called from loadEmbeddedFont which is called from e.g. PrismFontLoader.loadFont with null name parameter.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Toolkit.getToolkit().getFontLoader().loadFont("PTSans.ttc", 16);
returns null. The following css fragment prints exception to the console:

@font-face {
 src: url("PTSans.ttc");

}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Font does not load.

ACTUAL -
Font should load
