Description

Creating a RollingFileAppender leads to creation of a RollingFileManager
which creates a PatternProcessor, which creates a PatternParser.
The PatternParser will start out a plugin find expedition on the classpath which takes some time.
This is done for every RollingFileAppender you create. In my case the log file naming pattern is always the same for all log files, so I do not see the necessity for this plugin finding expedition. For instance PatternLayout does not do this as long as you supply a Configuration object which reuses the PatternParser for this Configuration object.
Can RollingFileManager follow the same pattern as PatternLayout does?
