A DESCRIPTION OF THE PROBLEM :
A call to java.net.InetAddress.getByName() in a separate thread trigger a cross domain check which result in daedlock.

REGRESSION. Last worked in version 9.0.4

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Frequently start a Java Web App which call InetAddress.getLocalHost(). In approx 30% it will hang.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
JStack produce the follow message:
