svn commit: r1577831 - in /tomcat/trunk: java/org/apache/tomcat/util/net/ test/org/apache/tomcat/websocket/ webapps/docs/config/

Author: remm
Date: Sat Mar 15 11:19:50 2014
New Revision: 1577831

URL: http://svn.apache.org/r1577831
Log:
- Cleanup and prefer non direct buffers for SSL by default (32KB of direct buffers per connection looks a bit too much).
- Give up on the SSL test for now.
