WICKET-5751 NullPointerException in IntHashMap
WICKET-5584 DiskDataStore error

> NullPointerException in IntHashMap
> ----------------------------------

> Key: WICKET-5751
> URL: https://issues.apache.org/jira/browse/WICKET-5751
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 7.0.0-M3
> Environment: Windows 7 Profession 64-bit
> Embedded Jetty 9.2.3.v20140905
> Reporter: Garret Wilson
> Fix For: 7.0.0-M5

> I was looking through a tester's log file to track down a separate issue. I
> came across a {{NullPointerException}} with {{IntHashMap}}, apparently when
> the server was shutting down.
> See also WICKET-5584, which also deals with a {{NullPointerException}} with
> {{IntHashMap}}, and also seems to relate to a {{null}} {{modCount}} (judging
> by the line number).
