On our Linux Centos server with API 2.9.7.1 Oracle Java 7 update 71
we are getting a large number of these exception patterns. I
haven't made any config changes lately, except to upgrade the
Java to update 71 which I assume would not be relevant.

Any ideas why? Maybe I should flush a cache?

Thanks! HyperScalper

So just for giggles I blew away the entire
JForex/.cache hidden folder tree and I'll see
whether that has any effect.

So far, it doesn't appear to change anything
and the exception still appears.

Just to provide another variation which might help clarify,
here on .readByte of DataInputStream

Thanks!

So, basically, you have made server-side changes which
are not upwardly compatible? If so, then I'll upgrade
the API version.

Thanks, HyperScalper
