Knut Anders Hatlen commented on DERBY-1095:
-------------------------------------------

The patch for ResultSet.isClosed() has to be updated because of a
conflict with the rearranging of the jdbc4 test suite. I will resolve
the conflict and commit the patch tomorrow.

> Closing an embedded connection does not seem to close associated

>      Project: Derby
>         Type: Bug
>   Components: JDBC
>     Versions: 10.2.0.0
>     Reporter: Kristian Waagan

> Closing an embedded connection (calling EmbedConnection.close()) does not 
> seem to close associated EmbedStatements. 
> The severity of the bug is not determined. The least severe case is that the 
> internal EmbedStatement variable 'active' is not updated accordingly, the 
> most severe case is that the the resources bound to EmbedStatement will not 
> be viable for garbage collection until the EmbedStatement itself is (if user 
> keeps references to it).
> If methods on the statement are called, Derby will correctly throw an 
> NoCurrentConnection exception, but the close() method is still never called 
> automatically.
> The problem also seem to extend down to ResultSet.isClosed(), but this is 
> probably due to the bug in EmbedStatement.
> Problem detected while fixing DERBY-953; implement Statement.isClosed().
