JTAPI thread goes into to stuck state and never returned
I am trying to set callforwarding on an address. The first request works fine and callforward gets set and any further requests on the same address does not processed

I tried setting first the callforward and then cancelling callforward. Cancellation never worked. tried multiple times by restarting my whole application.

When taken a thread dump , it shows the first callforward request holds lock on a vector object and second callforward request waiting for lock release.

code used

ITsapiAddress addr = (ITsapiAddress) getProvider().getAddress(userAddr);
CallControlForwarding[] ccf = new CallControlForwarding[1];
ccf[0] = new CallControlForwarding(destination,CallControlForwarding.FORWARD_UNCONDITIONALLY);
addr.setForwarding(ccf);

cancellation
addr.cancelForwarding();

It looks like you are using a JTAPI event thread to make the setForwarding() request.

You should not use a JTAPI thread to make a request to the API. You must always release the JTAPI event thread immediately and continue event processing (and making API calls) in a different thread.

Hi Martin,

it not a JTAPI thread.
The thread is initiated by my application for sure. and the callforwarding command is not set on an event alert

I was not able to reproduce your problem in my lab. I suggest you try using the latest version of the JTAPI client. If that does not fix your problem, you can open a ticket using the "Technical Support" menu item on the left side of this webpage. Make sure to include all the JTAPI traces and a sample of code that causes the problem.
