-----------------------------------------------

                 Key: OPENJPA-761
                 URL: https://issues.apache.org/jira/browse/OPENJPA-761
             Project: OpenJPA

            Priority: Minor

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.
