[news.eclipse.platform] Irregular expressions?

[John J Barton <johnjbarton@xxxxxxxxxxxxxxx>]

I got an odd error message:

The value of attribute "regex" associated with an element type 
"consolePatternMatchListener" must not contain the '<' character.	

But it seems that regex is supposed to be a java.util.regex.Pattern, 
which does not use < as a special character as far as I can tell.

Anyone know what kinds of expressions are allowed in 
"consolePatternMatchListener" extension points?

Thanks,
John.
