[Rxtx] RXTX Version mismatch

[depmar at poczta.onet.pl]

I downloaded rxtx library ver 2.2 from http://rxtx.qbang.org/pub/rxtx/rxtx-2.2pre2-bins.zip
Under Windows I have warning message, when I try to use rxtx for serial communication.

WARNING:  RXTX Version mismatch
?Jar version = RXTX-2.2pre1
?native lib Version = RXTX-2.2pre2

Could you help?
