FULL PRODUCT VERSION :


ADDITIONAL OS VERSION INFORMATION :
Environment:
  OS:windows8.1 pro (both 32bit and 64bit)
  JRE:Java7u2(32bit) and later

A DESCRIPTION OF THE PROBLEM :
Description:
GraphicsEnvironment API does not detect dynamically attached graphics device

how to reproduce:

1. start application under JNLP
2. attach new graphics device
3. can't obtain "currently" attached���device through GraphicsEnvironemnt API

It works fine on jre6/jre7u2 or earlier.
