Subject [jira] Updated: (DERBY-1095) Closing an embedded connection does not seem to close associated EmbedStatements
Date Fri, 10 Mar 2006 16:34:40 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1095?page=all ]

Kristian Waagan updated DERBY-1095:
-----------------------------------

    Attachment: Derby1095Repro.java

Simple repro for demonstrating the issue. Compile and run with JDK 1.6. Derby must also be
built with JDK 1.6.
The repro will fail with a "java.sql.SQLTransientConnectionException: No current connection"
as long as the issue exist.
When the issue is fixed, it should simply print two lines saying both the connection and the
resultset is closed.

> 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().
