svn commit: r1655120 - in /tomcat/tc8.0.x/trunk: ./ java/org/apache/catalina/authenticator/DigestAuthenticator.java webapps/docs/changelog.xml

Author: fschumacher
Date: Tue Jan 27 19:30:52 2015
New Revision: 1655120

URL: http://svn.apache.org/r1655120
Log:
Remove volatile from variables, as it is misleading. All
variables, that are mutable and read/written from different threads are only
modified/read within a synchronized block. All other variables are immutable
and are now declared final. Issue identified by Coverity Scan.

Merge r1654851 from /tomcat/trunk
