Sametime Proxy 11.5IF1 issues with iNotes integration

I updated the Sametime Proxy server 11.5 to IF1 for a customer, and the integration with iNotes broke.
When a user tried to start a chat with another user he received an error

I searched about this and I found some references to the Tomcat settings
org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH and org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH
looks like by default are set to false and this is the cause of the error. The URL you see in the image should be converted to sametime.company.it:8443/chat/conversations without the trailing part with the user name, but it doesn’t.

To resolve the issue edit the catalina.properties file in the sametimeproxy/conf directory and at the bottom add those two lines

org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true
org.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH=true

Restart the Proxy server and the chat works from iNotes.
