Multiline string literals are highlighted incorrectly when they contain blank lines

According to the spec, (https://openjdk.java.net/jeps/378) blank lines are excluded from "determining lines" when calculating indentation to strip.

"Blank lines – lines that are empty or are composed wholly of white space – have no visible influence on the indentation."

NetBeans highlighting does not do this and highlights extra leading spaces as if they are included in the string when there are blank lines that are completely empty or contain less spaces than the correct indent amount.
