In JBoss 5.x you used to be able to specify a suffix attribute value for the JBossWeb access log file, which would be appended to generated log file names.

In JBoss 7.x you can only specify a prefix. For the logging handlers you can specify both a prefix and a suffix, which is inconsistent.

Please add the suffix attribute to the access-log element within the parent virtual-server element of the web subsystem xml configuration.
