Re: [Quickfixj-users] NullPointerException in QFJ 1.0.2 that didn'tused to exist in 1.0.0-final

[Steve B. <st...@te...>]

Hello Toli,

It appears that somehow block() is processing a message and session
object is null. I've looked at the code and I don't see how this would
happen. Is it possible for you to send me your failing unit test
failing (off list)? If not, is your application an acceptor or an
initiator? Is there anything relevant in the log file?

Thanks,

Steve
