strange jmeter warning

[James Liang <jl...@andera.com>]

Hi all,

I wrote a very simple BeanShell Preprocessor at the global scope.  My test has 3 http samplers.  The first two sampler works fine but the third has strange warning.

Here is preprocessor beanshell code.  It looks for "cid" argument and replace it with a value from the user variables.


import org.apache.jmeter.config.Arguments;
log.info("preprocess: " + sampler.getPath());
Arguments args = sampler.getArguments();
if (args == null)
               return;

log.info("before args : " + args);

if (args.getArgumentsAsMap().containsKey("cid")) {
               log.info("found old cid, replace with new");
               args.removeArgument("cid");
               args.addArgument("cid", vars.get("CID"));
}

log.info("after args : " + args);



Here is log:
# sampler 1

2013/11/27 21:12:27 INFO  - jmeter.util.BeanShellTestElement: before args : prod=regression_checking

# sampler 3
2013/11/27 21:12:28 WARN  - jmeter.protocol.http.sampler.HTTPSamplerBase: Unexpected argument type: org.apache.jmeter.config.Argument

Notice there are no warning in the log for sampler 1 and sampler 2.  However, sampler 3 has a  warning.  I have no idea where that came from.
