under jEdit 2.6pre2, the Console plugin fails to instantiate its OptionPane, due to the removal of the FontComboBox class, on which it depends, from jEdit 2.6pre2.
this can be solved either by moving Console to the new FontSelector, thus breaking compatibility with jEdit 2.5, or by including the old FontComboBox from earlier versions of jEdit until Console is ready to require the 2.6 series.
Fixed in Console 2.1.3.
