I want to give +1 though I don't know I can do it or not...


BTW, I have a interesting bench mark data about Hotspot. 

Jakarta ORO 2.0.1            747 281 
Jakarta Regexp 1.2          1005 721 

left:  processing time before optimized by Hotspot 
right: processing time after optimized by Hotspot

JVM: Blackdown JDK1.3fcs
OS : Linux 2.2.17
CPU,MEM: PentiumII 266,128M

I have Japanese page that introduce it, 
http://www.mycgiserver.com/~tora/java/regexp.html

Sorry, I can't explain this contents at this moment in English.
(Maybe I need more time. I'm not good at English...)

But it's clealy, if the implementation of CharStringPointer close
Regexp's CharacterIterator, the performance which is optimized by
Hotspot will be much down.

We may want CharStringPointer then good performance because the
recent computer is enough fast.

regards.
