The system property petals.log.dir contains the default value used as base directory for Petals file log handlers, and it must be defined as an absolute value.
The absolute value is required by the Petals log handler PetalsPayloadDumperFileHandler. It flush message content in separated files and flush in the log file these files as relative paths.
Add support for a relative path: an absolute path will be built resolving the relative path of petals.log.dir against the current user directory
Improved in trunk
