Issue using Oracle Proxy user with JDBC OCI

Hi

I’m trying to use proxy user connect with liquibase and oracle 12 and its not using the proxy user but using the username specified in properties file instead. I saw this in one of the discussion, where it mentioned oci driver must support this, however doesn’t seem to work in my case. Any help on this is appreciated.  I had earlier reported this in Jira on July 3rd and havent seen any responses. Not sure which one of the two is the right forum for such questions Unexpected error running Liquibase: Validation Failed:
1 preconditions failed
changelog.xml : RunningAs Precondition failed: expected LBDEMO, was ORAXXX
