When running with fastdebug binaries we run intermittent into the issue below in
jtreg test java/awt/image/MultiResolutionImage/MultiResolutionImageObserverTest.java .
Seems we miss checking of successful HBITMAP creation before calling GetDIBits ?

  HDC hBMDC = this->GetDC();
  HBITMAP hBM = ::CreateCompatibleBitmap(hBMDC, 1, 1);
  VERIFY(::GetDIBits(hBMDC, hBM, 0, 1, NULL, gpBitmapInfo, DIB_RGB_COLORS));

in awt_Win32GraphicsDevice.cpp . Thats why the releast of hBMDC / hBM fails as well at the end of the function causing the seond and third warning.
