Hi,
When I deploy my geotools app on Glassfish server I'm getting a *lot* of
warning about streams being left open and not explicitly closed.
Some of these seem to be being produced from very simple things (eg.
instantiating a GridSampleDimension).
For instance here's a stack trace I'm getting :
WARNING: Input stream has been finalized or forced closed without being
explicitly closed; stream instantiation reported in following stack trace

And here's the line of code calling that :
GridSampleDimension dimension = new GridSampleDimension(dataset.getName(), new
Category[] { category }, null);
I can't see anywhere where I could possibly be closing that stream myself, so
I'm not sure what to do. It looks like I'm leaking a stream every single time I
call new GridSampleDimension, which doesn't seem sustainable - though I haven't
run my app long enough yet to actually have it run out of resources.
There are also a lot of other places where I'm having the same issue - for
instance I filed this bug ( http://jira.codehaus.org/browse/GEOT-2959 ) along
with a patch in 2010, but the issue is still marked as open. Am I missing
something here, or is geotools just designed to leak a lot of streams (maybe
it's not as bad as it sounds and these threads get cleaned up by the system
eventually anyway....) ?
cheers,
Josh
