Hi Krishna,

The changes I made is available on trunk. Basically I just set the timezone of the com.atlassian.xmlrpc.ConnectionInfo object to default to prevent NPE.

In trunk, we upgraded the version of atlassian xmlrpc which now uses a different Binder class and instead of using a plain com.atlassian.xmlrpc.AuthenticationInfo where you can only set the username/password, it now uses a com.atlassian.xmlrpc.ConnectionInfo.
