Hi
This sounds like a bug in JMeter, you should not get a nullpointer
exception.
I suggest you report the bug using bugzilla for JMeter.
Please include a step by step description of how to reproduce the
problem, it makes it easier to reproduce, fix and verify the fix for us.
It would be nice if you could include the stack trace for 2.3rc, since
that is where it is most likely we will fix the problem.
The jmeter.properties file is only read on startup of JMeter.

Hi Sebb-
Is there a library that I need to load to get access to the
httpclient.socket.http.cps related methods? If so, how would I do that?
If not, then why do I get a null pointer exception every time I enable
this feature with Jmeter 2.2 and 2.3?
Is the bandwidth constraint applied on a per thread basis, or across all
the threads cumulatively?
Thanks,
Alan

Subject: Can't adjust characters per second
I tried using the characters/second setting in the jmeter.properties
file. My recollection is that this only works with the commons HTTP
client. Is that correct?
When I set cps to 10000 cps using the following statements in
jmeter.properties
httpclient.socket.http.cps=10000
httpclient.socket.https.cps=10000
then I get a null pointer exception for every http request that I make
using the HTTP Request HTTPClient sampler.

The HTTP Request HTTPClient works fine when the lines above are
commented out.
I am running jmeter 2.1. Is this bug fixed in 2.3?
I also have a question about when jmeter reads the jmeter.properties
file. I am assuming that jmeter only reads this file when it is first
started. Is this correct?
Thanks,
Alan
