Lily Wei updated DERBY-5043:
----------------------------

    Attachment: Repro2905.java

Thanks Rick. When deregister=true, user need to do either “new org.apache.derby.jdbc.EmbeddedDriver();” or “Class.forName(driver).newInstance();”  in order to obtain a new connection.  When deregister=false, user can just obtain a new connection without issue Class.forName(). The default behavior is deregister=true. I am also attaching Repro2905.java to reference easy test case.

> With DERBY-2905, we have a new connection url attribute - deregister. After a shutdown of the embedded driver, the AutoloadedDriver is unregistered from the DriverManager. Users who wish to keep the AutoloadedDriver can set the deregister attribute on the connection url to false. It is only valid with shutdown=true. And, the default behavior with shutdown=true is deregister=true. 
> For example: 
> 'shutdown=true;deregister=true" (It is okay not to specify deregister=true)
> 'shutdown=true;deregister=false"
