["Knut Anders Hatlen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DERBY-2707?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Knut Anders Hatlen updated DERBY-2707:
--------------------------------------

    Attachment: jdbc4test.diff

Attaching patch which fixes the tearDown() method in the following files:
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/BlobTest.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/ClobTest.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/CallableStatementTest.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/TestJDBC40Exception.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/PreparedStatementTest.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/ResultSetTest.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/DataSourceTest.java

There is also a problem with tearDown() in LobStreamsTest and BlobSetMethodTest, but those tests are fixed in a patch that is attached to DERBY-2247, so I won't touch them here.

> Many of the JUnit tests under the jdbc4 package don't implement tearDown() properly. Common problems:
>   * don't close JDBC objects
>   * don't call super.tearDown()
>   * don't null out instance variables
