[PATCH] 8035653: jdk8u152-b01 windows crash on DatagramSocket.getLocalAddress

[Alex Kashchenko]

Hi,

We found that 8035653 test from jdk9 [1] crashes jdk8u152-b01 on windows 
at this point [2] because "ia6_class" is not initialized.

It looks like the following bit of 8035653 is missed in jdk8u152-b01:

      CHECK_NULL(IO_fd_fdID);

  }

If it will be convenient, I can submit an issue+webrev and re-send this 
to jdk8u-dev list. But as 8u152 is not yet released and the fix is 
already in jdk9, I will appreciate some guidance on this problem.
