uknown entities if the database cannot be accessed on initialisation
--------------------------------------------------------------------
Key: OPENJPA-2139
URL: https://issues.apache.org/jira/browse/OPENJPA-2139
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Mark Struberg
Assignee: Mark Struberg
Priority: Critical
Fix For: 2.3.0
The following scenario:
1.) turn off the database
2.) perform a query against the database
3.) turn on the database
4.) try to re-run the query from 2.)
In 4.) you will get the following Exception:
openjpa-2.2.0-r422266:1244990 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: An error occurred while
parsing the query filter "SELECT k FROM DbEnumKey AS k where k.type=:typ ORDER
BY k.ordinal". Error message: The name "DbEnumKey" is not a recognized entity
or identifier. Known entity names: []
Basically the whole app is stale afterwards!
Solution: caching the entities might only be done if a connection can be
established.
