Communicator ThreadSafe/proper use

glennleidy

I am using the java ice library.

I have found out ( rather painfully ) that the below statement
actually starts a background thread

Communicator communicator = Ice.Util.initialize();

and if one does not do

communicator.destroy()

a thread leakage problem occurs.

Currently I use a single communicator for each slice related thread I have
and I was not executing the destroy() method so when the thread ended I had
orphan "communicator" thread.

Can I use a single "communicator" for all threads in a JVM ( it is thread safe )
or should I make sure I am calling the destroy() method for each "communicator"
that I instantiate via Ice.Util.initialize() ?

Thanks,
Glenn

Hi Glenn,

Calling destroy is indeed required to free resources allocated by the Ice communicator, for more information on this, see the Ice communicator documentation here.

It is fine to create a single communicator which is shared by multiple threads, this is the recommended way to use the communicator (an application should rarely need to create multiple communicators).

Cheers,
Benoit.

Thank you. This is what I was hoping for.
