Sth wrong with Bulk when build index action with String-type source

[Weijianlin]

when build index action with String-type source, function generateBulkPayload of Bulk will delete all whitespace of the source:
// line 95 in Bulk.java
if (source instanceof String) {
return StringUtils.deleteWhitespace((String) source);
}

if the soure is a json string like {"text": "a b c"}, the whitespace in the value will be deleted.

Should I not build Index with string-type source?
