Ran into a deadlock in Appcelerator Studio after the following steps:
1. Launch Studio and log out;
2. Launch Studio, enter proxy settings (https://wiki.appcelerator.org/display/tools/Internal+Proxy+Server) and log in;
3. Have a tiapp.xml open and re-launch Studio.
After Studio is re-launched, it would beach-ball and had to be force-killed. And each time afterward, Studio would freeze upon launch.
Attached the jstack log.
