Inconsistency in JsonParser#hasNext()

[leadpony]

hasNext() method in JsonParser provided by the Reference Implementation does not behave consistently for unterminated JSON.
Please see the following results.

No.	JSON to parse	Result of hasNext()
1	(empty)	hasNext(); // returns true 😕
2	{	next(); hasNext(); // throws JsonParsingException
3	{"a"	next(); next(); hasNext(); // throws JsonParsingException
4	{"a":	next(); next(); hasNext(); // returns true 😕
5	{"a":1	next(); next(); next(); hasNext(); // throws JsonParsingException
6	{"a":1,	next(); next(); next(); hasNext(); // returns true 😕
7	[	next(); hasNext(); // throws JsonParsingException
8	[1	next(); next(); hasNext(); // throws JsonParsingException
9	[1,	next(); next(); hasNext(); // returns true 😕

I believe for No.1, 4, 6, and 9 case, hasNext() should throw JsonParsingException instead of returning true.
Are these correct and intended bahavior?
