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.

Do you want to break into the debugger? ********************* ********************* AWT Assertion Failure ********************* ::DeleteObject(hBM) File 'e:\openjdk\openjdk-21u-windows_x86_64-dbg\jdk\src\java.desktop\windows\native\libawt\windows\awt_Win32GraphicsDevice.cpp', at line 297 GetLastError() is 57 : The parameter is incorrect. So it seems, we should have some additional checks/tracing. ------------- Commit messages: - JDK-8320405 Changes: https://git.openjdk.org/jdk/pull/17197/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=17197&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8320405 Stats: 14 lines in 1 file changed: 12 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/17197.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/17197/head:pull/17197 PR: https://git.openjdk.org/jdk/pull/17197
