shou aoki updated SOLR-3790:
----------------------------
Description:
Hi, Im using Solr 3.5.
I found strange phenomenon in solr log.
This phenomenon has two exceptions that NullPointerException and
ConcurrentModificationException.
These exceptions are thrown by discrete threads.
I think, The same two queries thrown at same time because error log recorded at
same time. But I can't reproduce it.
Does anyone have the same phenomenon?
