RMI with Java inside Wine?

[PowerStat]

Hello,

I am trying to run the following setup:

Debian 7
Wine 1.4.1
Java 7u67
My own JAVA RMI-Server Program - starts already

now I am trying to connect this with a java RMI-client - which fails.
Network connections from outside Linux work fine (http). No firewall active.
Also I can telnet port 1099 (RMI) from outside.
No Exceptions found.

So I wonder why I can not bring the RMI-client to work with the server inside wine?
Windows/Windows RMI works since months.

Thanks for help in advance.

Btw. before someone is asking why I am doing it this way - the server RMI uses a windows dll for which I have no source and which is only available for Windows 32Bit So my idea is to decouple this dll from the rest of my code to made it run native under Linux The code already runs under Windows 64Bit/Java64 with this decoupling.

Meanwhile I found it myself - /etc/hosts was on 127.0.1.1 instead of the correct DHCP IP - seems that this hostname -i value was used by RMI as answer for the followup after requesting the registry.

So now I am hanging, because Visual Studio Runtime 2012 has status GARBAGE
