      Description

      This bug was found when doing soft upgrade testing from Derby version 10.4.2.0 to 10.5.1.0 (RC1)

      Steps followed are as follows.

      1. Run setEmbeddedCP.bat from version 10.4.2.0's bin folder
      2. In a test folder run ij
      3. create system/wombat database.
      ij> connect 'jdbc:derby:system/wombat;create=true';
      4. exit ij
      5. Copy the 10.5.1.0 derby jars (from lib folder) and the derbyTesting.jar from 10.4.2.0 to the test folder and set classpath with them (including junit and ORO)
      6. Run suites.All
      java -Xmx512M -Xms512M -Dderby.tests.trace=true junit.textui.TestRunner org.apache.derbyTesting.functionTests.suites.All

      Result:
      Tests run: 10479, Failures: 56, Errors: 34

      The stack trace is as follows.

      I did not see anything in the derby.log from the tests that seemed to be related to this.

      Note that this test passed when run by itself, and also when run after a couple of failing tests (namely org.apache.derbyTesting.functionTests.tests.jdbcapi.BlobClob4BlobTest and org.apache.derbyTesting.functionTests.tests.jdbcapi.UpdatableResultSetTest)
