    <p>choosedevice ...  OpenJDK 64-Bit Server VM warning: You have loaded

    It's highly recommended that you fix the library with 'execstack -c
    ', or link it with '-z noexecstack'. Exception in thread

  <p>By the way I tried to execute " execstac -c " it doesn't work at all
  Also I spent days trying to figure out the solution , the only conclusion i come up with so far , is i need to use libjnetpcap.so (64 bit) since i have 64 bit architecture on my Debian .
  so is that what i need to do ?</p>
  
  <p>PS : I can't find any ".deb" to install this library for 64 bit.</p>
