RFR: JDK-8320405: [Windows Server 2016] java/awt/image/MultiResolutionImage/MultiResolutionImageObserverTest.java shows issues in awt_Win32GraphicsDevice.cpp

[Matthias Baesken]

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.

GetLastError() is 57 : The parameter is incorrect.

Do you want to break into the debugger?

So it seems, we should have some additional checks/tracing.
