NetBeans Under OpenJDK 7 On OS X - Dual Display

[Max (Weijun) Wang]

Sorry, my previous analysis is wrong. The problem seems to be in  
NET_timeout.

I noticed some lines in hotspot/src/os/bsd/vm/hpi_bsd.hpp
http://hg.openjdk.java.net/bsd-port/bsd-port/hotspot/file/4244db6cd9a9/src/os/bsd/vm/hpi_bsd.hpp

#ifdef __APPLE__
     // XXXDARWIN: poll() appears non-interruptable on Leopard:  
Thread.interrupt() failed to
     // cause interrupt. Does poll work at all on Tiger? Needs  
investigation.
     fd_set fdset;
     struct timeval seltv;

     FD_ZERO(&fdset);
     FD_SET(fd, &fdset);

     seltv.tv_sec = timeout / 1000;
     seltv.tv_usec = (timeout % 1000) * 1000;

     INTERRUPTIBLE_NORESTART(::select(fd+1, &fdset, NULL, NULL,  
&seltv), res, os::Bsd::clear_interrupted);
#else
     struct pollfd pfd;

     pfd.fd = fd;
     pfd.events = POLLIN | POLLERR;

     INTERRUPTIBLE_NORESTART(::poll(&pfd, 1, timeout), res,  
os::Bsd::clear_interrupted);
#endif

In fact, if I remove the #if part and revert to the #else block.  
Everything works again. I'm using OS X 10.5.6 on a 32bit Core Duo  
MacBook.

Thanks
Max
