Hi,
my trace file contains some "connection not closed" warnings:
08-29 07:06:13 jdbc[4]: connection not closed

<my source code stack trace>
I tried to check why my application does not close the connections but
didn't really find anything (I am quite sure I've looked at the wrong
place ;-).
Now I have some questions:
1. Is it correct that the stack trace of the error message shows the
stack trace of the time when the unclosed connection was opened?
2. When and how does H2 detect that a connection from a connection
pool is not closed?
3. Sometimes my application closes and reopens the database. Do I have
to call the dispose method of the old JDBCConnectionPool? I haven't
done that because it's not part of the DataSource interface.
So the schematic code looks like:
DataSource pool = JdbcConnectionPool.create(url, user, password);
... do lots of things ...
... ensure that no more connections are open ...
... close the database using a "SHUTDOWN" command ...
// do I have to call?
// ((JDBCConnectionPool)pool).dispose();
pool = null;
pool = JdbcConnectionPool.create(url, user, password);
