New issue 192 by howardm...@screamingcoder.com: Jackson/JSON errors
iterating over resources using restcomm-java-wrapper 1.0.0.FINAL
http://code.google.com/p/restcomm/issues/detail?id=192

What steps will reproduce the problem?
1. Install RestComm
2. Connect to it using the restcomm-java-wrapper, using the default Account
3. Query the list of accounts and try to iterate over them, printing the
account SID to stdout.
Alternatively, add one or more IncomingPhoneNumbers to the default Account
and try to iterate over those.

What is the expected output? What do you see instead?
There should be one Account's SID printed to stdout (the default account
included in RestComm), or multiple IncomingPhoneNumber's SIDs.

What version of the product are you using? On what operating system?
- RestComm Tomcat 1.0.0.Final (which unzips into a
restcomm-sass-tomcat-1.0.0.CR1 directory, FYI)
- org.mobicents.servlet.sip:restcomm-java-wrapper:1.0.0.FINAL


Please provide any additional information below.
I have attached a simple maven project which reproduces the error against
the default RestComm installation when you build the project and the unit
tests are run. The tests assert that the list of Accounts and the list of
IncomingPhoneNumbers are not empty. The former should contain the default
account, the latter should contain IncomingPhoneNumbers which the test has
added to the default Account just prior to looking them up again. You may
need to update the AppTest.java:RESTCOMM_URL constant if running RestComm
on a different host or port.

Sorry, forgot "What do you see instead?"

I see the below stack trace in the console, and no SIDs, as if both the
client.getAccounts().iterator() and the
client.getAccount().getIncomingPhoneNumbers().iterator() have returned
empty collections.
