StringBuffer.append() being called with an array and not a String

[scuniff]

Lines 183 to 186 in da3a5f3

	buffer.append(" .unknown = ")
	.append("0x").append(HexDump.toHex( field_2_unknown ))
	.append(" (").append( field_2_unknown ).append(" )")
	.append(System.getProperty("line.separator"));

Line 185 should use HexDump.toHex() like in line 184?

.append(" (").append(HexDump.toHex( field_2_unknown) ).append(" )")
