Description Markus Schönhaber 2005-07-30 18:26:37 UTC 
When using AJP and APR, a NPE occurs in 
ServletRequest#getAttribute("javax.servlet.request.cipher_suite");
When accessing the bundeled example-servlet
/servlets-examples/servlet/RequestInfoExample
this can be observed.

The statcktrace:

I've verified this on a stock Tomcat 5.5.10 binary distribution connected to an
Apache httpd 2.0.54 using JK-1.2.14.

If APR is not used, no Exception is thrown.
