[jira] Commented: (OPENJPA-1801) CacheStatistics misses are
improperly calculated.
[ https://issues.apache.org/jira/browse/OPENJPA-1801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12918238#action_12918238 ]
Pinaki Poddar commented on OPENJPA-1801:
----------------------------------------
from JavaDoc of CacheStatistics
* All methods with Class as input argument treats null as
* <code>java.lang.Object</code>. All per-class statistics depends on
* determining the runtime type of the instance being cached. If it is not
* possible to determine the runtime type from the given context, the statistics
* is registered under generic <code>java.lang.Object</code>.
*
* @since 1.3.0
> CacheStatistics misses are improperly calculated.

> In doing some testing I found that the DataCache statistics aren't calculated properly. In the case where there is a cache miss for a specific Type(Person.class), a miss (a read with no subsequent hit) is recorded for java.lang.Object.
