Michael McCandless commented on LUCENE-1500:
--------------------------------------------
bq. What did you think of my suggestion to fix this problem at it's source -
i.e. Token should never be in a state with end<start in the first place?
I'm wary of this, for the same reason as cited above. I think the
start/end offsets are rather opaque to Lucene, and I would lean
towards asserting as little as possible about them during indexing.
(Not to mention the challenges, as you enumerated, of actually doing
this checking with the current API).
I think at point-of-use (highlighting) we should assert the offsets
are valid, for highlighting.

> Project: Lucene - Java
> Issue Type: Bug
> Components: contrib/highlighter
> Affects Versions: 2.4
> Environment: Found this running the example code in Solr (latest
> version).
> Reporter: David Bowen
> Assignee: Michael McCandless
> Fix For: 2.9
>
> Attachments: Lucene-1500-NewException.patch, LUCENE-1500.patch,

>
> Using the canonical Solr example (ant run-example) I added this document
> (using exampledocs/post.sh):
> <add><doc>
> <field name="id">Test for Highlighting
> StringIndexOutOfBoundsExcdption</field>
> <field name="name">Some Name</field>
> <field name="manu">Acme, Inc.</field>
> <field name="features">Description of the features, mentioning various
> things</field>
> <field name="features">Features also is multivalued</field>
> <field name="popularity">6</field>
> <field name="inStock">true</field>
> </doc></add>
> and then the URL
> http://localhost:8983/solr/select/?q=features&hl=true&hl.fl=features caused
> the exception.
> I have a patch. I don't know if it is completely correct, but it avoids this
> exception.
