Subject [jira] [Created] (LUCENE-3529) creating empty field + empty term leads to invalid index

creating empty field + empty term leads to invalid index
--------------------------------------------------------

                 Key: LUCENE-3529
                 URL: https://issues.apache.org/jira/browse/LUCENE-3529
             Project: Lucene - Java
          Issue Type: Bug
    Affects Versions: 3.4
            Reporter: Robert Muir


Spinoff from LUCENE-3526.

* if you create new Field("", ""), you get IllegalArgumentException from Field's ctor: "name
and value cannot both be empty"
* But there are tons of other ways to index an empty term for the empty field (for example
initially make it "garbage" then .setValue(""), or via tokenstream).
* If you do this, and you have assertions enabled, you will trip an assert (the assert is
fixed in trunk, in LUCENE-3526)
* But If you don't have assertions enabled, you will create a corrupt index: test: terms,
freq, prox...ERROR [term : docFreq=1 != num docs seen 0 + num docs deleted 0]
