Sorry your bug didn't get noticed for so long. Are you using the source version 
and recompiling for 1.5? I believe you should be using Java 6 for 
google-voice-java. Download the source and compile from that to see if it gives 
you any issues.

I have seen no follow up on this, and this version 1.6 is no longer supported.  
I am therefore closing the issue.  If anyone can find a legitimate issue that 
is still present here and has not been fixed by a later version we can reopen.
