JDK 8 Code Review Request for 7195301: XML Signature DOM implementation should not use instanceof to determine type of Node

[Sean Mullan]

Hi Xuelei,

Would you be able to review my fix for 7195301?

webrev: http://cr.openjdk.java.net/~mullan/webrevs/7195301/webrev.00/

No regression test (noreg-hard), requires complex setup, but I have attached a
test to the bug report that can be run manually.

Thanks,
Sean
