Which OpenJDK build was this? I'm curious because Windows Sockets calls 
are never interrupted so that error should never be returned. Any chance 
the application in question is in a loop creating SocketChannels and 
calling connect (perhaps catching and ignoring an IOException). Just a 
guess. It would also be interesting to know if this happens outside of 
the profiler.
