ModeShape Tools has a dependency to a ModeShape client library. This library uses SLF4J for its logging and depends on an SLF4J logger implementation to be available at runtime. ModeShape Tools has implemented a logger that will redirect the ModeShape logging to the Eclipse logger. Problem is that all levels of logging are always being logged regardless of the logging level of the running Eclipse. So lots of trace-level messages are appearing in the Eclipse log. Another problem is that Eclipse does not have trace-level logging.
