jEdit : Highlighter plugin to mark sequences in a logfile

jEdit has a nice plugin named highlighter. This plugin allows you to select an
( regular ) expression which should be highlighted with a user defined color.


In this screenshot you see the highlighter attached at the bottom and some
expressions, which are highlighted in the log file ( in this case different threads
are shown ).
Each expression can be defined, if it is only for the buffer ,session or permanent
usage.
