Raintung Li commented on SOLR-5661:
-----------------------------------
If you have multiple shard for one collection, send the query url for max
integer rowid, it can easy replicate.
Caused by: java.lang.OutOfMemoryError: Requested array size exceeds VM limit

> PriorityQueue has OOM (Requested array size exceeds VM limit) issue
> -------------------------------------------------------------------

> Key: SOLR-5661
> URL: https://issues.apache.org/jira/browse/SOLR-5661
> Project: Solr
> Issue Type: Bug
> Components: contrib - Solr Cell (Tika extraction)
> Affects Versions: 4.3.1, 4.4, 4.5, 4.5.1, 4.6
> Environment: JDK 7
> Reporter: Raintung Li
>
> It look like JDK7 change the design for max_array_length logic, it isn't
> max_jint, and it should be max_jint - header_size(type).
> If you deliver the Integer.MaxValue to create the PriorityQueue and have
> enough memory, you will find it is ok in JVM6 but not work in JVM7.
>
> JVM7 will throw OOM error while do array rang checking.
> It should the compatible issue between JVM6 and JVM7.
> Maybe need protect in the code logic, throw OOM look like big issues for
> customer.
