Hi, > 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?
Yes, but for a pooled connection that might be the wrong place. > 2. When and how does H2 detect that a connection from a connection > pool is not closed? Older versions of H2 used a finalize method, but newer versions use a PhantomReference because that's faster. See also the source code (org.h2.util.CloseWatcher). > 3.

Yes. > I haven't done that because it's not part of the DataSource interface. I see. To me this looks like an omission in the API. There are at least two other connection pools that support 'dispose': http://cayenne.apache.org/doc12/api/cayenne/org/objectstyle/cayenne/conn/PoolManager.html#dispose() others use 'close': http://commons.apache.org/dbcp/apidocs/org/apache/commons/dbcp/datasources/SharedPoolDataSource.html#close() Regards, Thomas -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
