ZOHO CRM JAVA SDK version 2.0.x - Setting Proxy In Configuration Property

ZOHO CRM JAVA SDK version 2.0.x - Setting Proxy In Configuration Property

We are currently using Java SDK version 1.0.6. We are looking to upgrade to the latest version of the library 2.0.1. In the latest version of the SDK it seems the property files zcrmconfiguraiton and oauthconfiguration are removed and replaced by property map. 

In the 1.0.6 version currently we are setting the following properties:
proxyHost=
proxyPort=
proxyUserDomain=
proxyUser=
proxyPassword=

 We do not see these being listed in the latest documentation. Can we still use them? This is very important to us since we cannot access ZOHO API without a proxy. 

Please confirm the proxy parameters are still supported in 2.0.1.
