Apache and mod_proxy not handling HTTP 100-continue from client HTTP 417

'm building some webby magic and am using Apache to front our tomcat server, forwarding requests to tomcat on port 8080. I have an issue using Apache and mod_proxy to forward requests. It appears the client (a web application) sends an HTTP 100-continue to which Apache responds with a 417 Expectation Failed.

When I take Apache out of the picture and send requests directly to tomcat on port 8080, the request is successful and the client is sent a 200 OK.

My Apache config looks like:

ServerName abcproxy DocumentRoot /apps/apache-content/default

AddOutputFilterByType DEFLATE text/html text/plain text/css application/javascript text/xml

BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

ExpiresActive on
ExpiresDefault "access 0 seconds"

ProxyPass / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/

        ProxyPreserveHost On

CustomLog /apps/ocp-logs/apache/abcproxy.log combined

Anyone see where i'm going wrong?
