FULL PRODUCT VERSION :
1.8.0_60

ADDITIONAL OS VERSION INFORMATION :
10.10.5

A DESCRIPTION OF THE PROBLEM :
Addition information for bug JI-9023785

Effectively when running on OS X Java 1.8.0_60 performs certain activities related to network functionality like jdbc communications and DNS operations very very slowly compared to the preceding version 1.8.0_51

REGRESSION. Last worked in version 8u51

ADDITIONAL REGRESSION INFORMATION:
1.8.0_51

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run sample code provided against Java 1.8.0_60 and Java 1.8.0_51 on the OS X platform and compare the response times.
