Richard Zowalla resolved OPENJPA-1447.
--------------------------------------
Resolution: Won't Fix
Closing as obsolete during backlog cleanup: The Kodo plural syntax was never
contributed, and the tests that used it stay commented out
(CacheTest.java:183-193); named multiple caches are now done with
PartitionedDataCache (openjpa-kernel datacache/PartitionedDataCache.java).
Please reopen if this still happens with OpenJPA 4.x.
> Plural configuration property processing
> ----------------------------------------
>
> Key: OPENJPA-1447
> URL: https://issues.apache.org/jira/browse/OPENJPA-1447
> Project: OpenJPA
> Issue Type: Sub-task
> Components: datacache
> Affects Versions: 1.2.1, 2.0.0-M3
> Reporter: Kevin W. Sutter
> Priority: Minor
>
> Two of the tests that I recently enabled via the parent JIRA (openjpa-1443)
> required a feature of the configuration properties that does not seem to be
> present in OpenJPA. After talking with Patrick, it sounds like Kodo has this
> capability, but it wasn't contributed to OpenJPA. Or, at least, that's how
> it looks...
> As an example, CacheTest, TestSJVMCache and TestDataCachePCDataGenerator
> expected the following configuration to create multiple DataCaches...
> <property name="DataCache" value="true, true(Name=xxx), true(Name=yyy)"/>
> Attempting to run these tests on trunk and 1.2.x resulted in the following
> error message:
> org.apache.openjpa.persistence.PersistenceException: Instantiation of plugin
> "DataCache" with value "true, true" caused an error
> "java.lang.IllegalArgumentException: java.lang.ClassNotFoundException: true,
> true". The alias or class name may have been misspelled, or the class may not
> have be available in the class path. Valid aliases for this plugin are:
> [concurrent, false, true]
> According to Patrick, this plurality capability should be applicable to all
> plugin configuration properties. So, when we fix this, we should do a
> general fix, not specific to the openjpa.DataCache property.
> When this JIRA gets resolved, we should re-enable the sections of test code
> in CacheTest, TestSJVMCache and TestDataCachePCDataGenerator. The following
> comment in these tests highlights the area in setup(), but this plurality
> feature was used in several locations in these tests...
> /*
> * OpenJPA does not seem to support plural configuration properties.
> (Although it seems
> * that Kodo does...) Until OpenJPA is updated to support this
> multiple configuration
> * setting, the following configuration item will be disabled...
> *
> * Specifically, this type of configuration is currently not
> allowed...
> * <property name="openjpa.DataCache" value="true, true(Name=xxx)"/>
> */
> Thanks,
> Kevin
