I was testing the login page of the portal on my 2.4GHz linux machine.  I
tested using JMeter with from 7 to 20 threads.  Before the change I was
able to get a throughput of about 3.9 requests/second.  After the change
it went to 5.4 requests/second.  The regexp is hardcoded in the
EncodeURLTransformer and did not change. The only change I made was to
replace RE with Pattern and the match call to match the JDK 1.4 syntax.

I ran a grep a while ago and found that there was one other place that
used Jakarta regexp. I think it was SourceUtil. I did not change that. 
Jakarta regexp is in the lib/endorsed directory.  I have no idea why.  I
presume some other package we are using requires it.

Maybe not, ie xalan needs regexp. :-S

So once all references in our code are gone it can be removed?

It is in the endorsed dir because an older version of it comes with the 
newer Sun JDKs (I think 1.5 and later). So we have the same problem as 
with the XML libs.
