Auto highlighting of multiple words interferes with normal selection and stays selected too long about jsyntaxpane HOT 3 CLOSED

Thanks for the report.  By default, auto-word highlighting can be disabled by
changing the jsyntaxpane.config.properties file under META-INF\services.
The file contains the "plugins" to use for any particular editorKit:

JavaSyntaxKit.components = jsyntaxpane.components.PairsMarker, \
    jsyntaxpane.components.LineNumbersRuler, \
    jsyntaxpane.components.TokenMarker

You can remove the TokenMarker, and it will not show.

I will look later at how highlighting interferes with selection and fix it.  But
might take a while.

You can also use the DefaultSyntaxKit.getConfig to get the configuration, then 
change
the above key/value before creating your EditorPane.  Convenience method to set 
a
property will be added to the class.
