I updated my machine to 10.9 and was not able to log in to studio.
I then reinstalled Studio (did this again to the latest release, today) and am still not able to log in.
Steps to reproduce:
1. Open Titanium Studio
2. Attempt to login
3. Witness the attached error
javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
