QueryCache don't allow for misconfigurations
Hi.
Might have found a "bug".
This could be replicated with a malformed persistence.xml. You have to
create a configuration without any classes specified then the QueryCache
will throw a null pointer exception.
104 test INFO [main] openjpa.Enhance - You have enabled runtime
enhancement, but have not specified the set of persistent classes. OpenJPA
must look for metadata for every loaded class, which might increase class
load times significantly.
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details.
212 test INFO [main] openjpa.Runtime - OpenJPA dynamically loaded a
validation provider.
292 test INFO [main] openjpa.Runtime - Starting OpenJPA 2.2.0

Hi all,
May be someone looks to other bug connected with Query Cache (to be
precise Prepared SQL Query Cache) :
https://issues.apache.org/jira/browse/OPENJPA-2147
Thank you in advance.
Sincerely,
Dmitry Pavlov
