Pipes etc.

 From one of the JXTA documents/books they are showing how to create and 
adv for
a pipe - which is straightforwad. I used that in parts of my 
applications. Now that I am
debugging I am finding out that one of the threads responsible for 
creating this pipe makes
the call to the first statement below and blocks ! Any reason why that 
would be happening ?
Should I scratch this below and use a flat file with the adv in it and 
simply load it ? Thanks much

PipeAdvertisement pipeAdv = 
(PipeAdvertisement)AdvertisementFactory.newAdvertisement(PipeAd
vertisement.getAdvertisementType());

pipeAdv.setName("JXTA:KEYRECEIVE");
pipeAdv.setType("JxtaUnicast");
pipeAdv.setPipeID((ID) 
net.jxta.id.IDFactory.newPipeID(netPeerGroup.getPeerGroupID()));
