Incorrect connection URL causes NPE when using JDBC Driver
----------------------------------------------------------
Key: OPENJPA-656
URL: https://issues.apache.org/jira/browse/OPENJPA-656
Project: OpenJPA
Issue Type: Bug
Affects Versions: 1.2.0
Reporter: Jeremy Bauer
Priority: Minor
If a JDBC URL is specified with an incorrect protocol or subprotocol in
combination with a JDBC Driver class when configuring a PU an NPE is thrown
within the OpenJPA code when trying to create an entity manager. The NPE
bubbles out to a not-so-useful PersistenceException with internal
StoreException containing message text "null".
For example: (note the missing colon after the subprotocol)
openjpa.ConnectionDriverName=com.ibm.db2.jcc.DB2Driver
openjpa.ConnectionURL=jdbc:db2//my.database.com:800/MYDB
Results in:
[java] <openjpa-1.2.0-SNAPSHOT-r422266:667312 nonfatal general error>
org.apache.openjpa.persistence.PersistenceException: There were errors
initializing your configuration: <openjpa-1.2.0-SNAPSHOT-r422266:667312 fatal
store error> org.apache.openjpa.util.StoreException: null
