Downgrading fixes the issue.

Sorry for the slow response.

Do you have some sample code to reproduce this? What is the exact version of the JDK you used? I just tried the client using the following Java version, and it seemed to work fine.

java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)

I have seen this happen very occasionally with 1.8.0_31. Apparently it is fixed in 1.8.0_40.

@cb372 Sorry, I didn't see the first message.

I think this was happening during compilation for me, so I don't really have any sample code. Going to 1.8.0_40 also fixed it for me.

OK, I'll go ahead and close this.
