OtpNode triggering IOException

I experience a strange problem. Sometimes our Java app will not start and will raise an IOException when trying to open a OtpNode. Here is the code (really nothing special):

OtpNode oNode = new OtpNode(NODE);
oNode.setCookie(COOKIE);       
OtpMbox mbox = oNode.createMbox(MBOX);

NODE, COOKIE and MBOX are hardcoded constants. The error I get is:

class java.io.IOException,
'Nameserver not responding on Martin-PC when publishing jnode',
Stack trace: [Ljava.lang.StackTraceElement;@c3ea5a

That's it. And this happens only sometimes. I observed that when restarting the PC it happens.

Had anyone seen similar problem?

Thank you.

It turned out that after restrat the Erlang virtual machine sometimes is not running. So we need to start it first before Java OtpNode could be started:

erl -sname whatever
