Re: [milo-dev] ClientServerExample.java failed and fix bug ?
Well I'm not sure what to do with this report. Your patch doesn't actually change any behavior, the error your reported is not reproducible by running the example, and the security policy URI really can't be greater than 255 bytes as per the spec, so even if you did encounter that the error is correct.

Hi Kevin,

Endpoint URLs of UaTcpStackServer is below:
-----
UaTcpStackServer startup - opc.tcp://localhost:12685/example bound to /127.0.0.1:12685 [None/None]
UaTcpStackServer startup - opc.tcp://localhost:12685/example bound to /127.0.0.1:12685 [Basic128Rsa15/SignAndEncrypt]

I tried to run ClientServerExample.java with Java8/Apache Felix 4.6.1
on Windows 7 (64bit) (using Netty 4.1.1.Final).

Regards,
