AxisClientProxy causes NullPointerException

[James Carman <ja...@carmanconsulting.com>]

I have a situation where I am getting a NullPointerException in the
AxisClientProxy.  In the proxyParams2CallParams method, there is no null
check on the proxyParams argument.  So, when it tries to iterate through the
array of objects, it gets a NullPointerException on the proxyParams.length
reference.  However, when I added in the logic to merely return null when
the argument was null, the application just hung completely.  Here's my
stack trace.  I built this version from the current CVS tree.
