Description

A test used the SchemaTool to reflect "all" schema in a Oracle DB but run in a NPE as observed below:

[exec] 131 INFO [main] openjpa.jdbc.JDBC - Using dictionary class "com.ibm.ws.persistence.jdbc.sql.OracleDictionary".
[exec] 1127 INFO [main] openjpa.Tool - Reflecting on schemas "all". This process may take some time. Enable the org.apache.openjpa.jdbc.Schema logging category to see messages about the collection of schema data.
