Hi experts,
Recently one of our customer continuously seeing ArrayIndexOutOfBoundsException
which is thrown from Lucene.
Our production is full-text search engine built on top of Lucene, following is
the stack traces. The customer saying that they can reproduce the issue even
after re-index everything from scratch.

==============================================================
The corrupted payload stores a serialized hashmap which contains several
configurable metadata which is used to sort by condition.
The field of the corrupted payload is single term field, so the structure of
posting looks like a sequence of payload.
We also put freshness boost value into payload in another field, which have no
issues.
It is the first customer report the corruption after we used Lucene 4.5.1 and
released our product for many years.
Please let me know if you have any idea to this issue.
Thanks,
Tony Ma(马江)
