| Re: [milo-dev] ClientServerExample.java failed and fix bug ? |
Hi Kevin,
ClientServerExample.java run successfully with Netty-4.0.36.Final.
But it failed to run with Netty-4.0.37.Final/Netty-4.1.1.Final and
output same stack trace.
I don't know why.
Do you reproduce this error with Netty-4.0.37.Final and Netty-4.1.1.Final ?
Regards,
--Shigeru
