android-json-rpc unable to resolve static field 253 (VERSION_2)
===

I try to call a JSONRPC webservice with android-json-rpc library, but my Eclipse logCat throw this warning:

 W/dalvikvm(344): VFY: unable to resolve static field 253 (VERSION_2) in Lorg/alexd/jsonrpc/JSONRPCClient$Versions;

This warning appears when I try to create the client: 
JSONRPCClient.create (URL, JSONRPCClient.Versions.VERSION_2);

Consequently it can not create JSONRPCClient.

Thanks in advance!,
