The messages displayed here are those written through Java's

debugging purposes and not for users to read, but if something
unexpected is happening, or if you are filing a bug report,
it may provide some clues about what's going on.
Although it tries not to disturb things too much, TOPCAT's
manipulation of the logging infrastructure affects how it is
set up, so if you have customised your logging setup using,
properties, you may find that it's not behaving exactly as
you expected. Sorry.
