When you look at the code it seems like a copy/paste error:

String subString = text.substring( lastOffset, i );
lastOffset = i + 1;

int lastComma = subString.lastIndexOf( "," );
if ( lastComma != -1 )

{ segments.put( subString.substring( 0, lastComma ).trim(), subString.substring( lastComma + 1 ).trim() ); }

else

{ segments.put( subString.substring( 0, lastComma ).trim(), null ); }

I guess the last line should read:

segments.put( subString.trim(), null );
