jawin output

I am using jawin to query wmi classes.

Everythying is working fine except I get some really annoying log
messages to stdout or stderr that I cannot find any documentation on how
to turn off.

They are as follows:
orgInvoke requestSize=4

This happens each time I make a call to wmi which is quite frequently
b/c I am iterating over a very large set.

Any ideas on how to turn off this logging?

Thanks,
Jon
