Subject NullPointerException when Shuting Down Derby
Date Mon, 28 Jan 2013 20:52:40 GMT
When I do the following it sometimes returns a NullPointerException:

      DriverManager.getConnection("jdbc:derby:;shutdown=true;deregister=false");

Here is the exception stack trace:

        at java.sql.DriverManager.getConnection(DriverManager.java:350)

Does anyone know why this is happening?

I am using Derby 10.8.2.3

Thanks,
