[Visual Studio 2026 May Update](https://learn.microsoft.com/en-us/visualstudio/releases/2026/release-notes#may-update-1860) (see C++ > MSVC Build Tools 14.51 > Standard Library (STL) > Other notable changes) removed support for some old, deprecated and non-standard STL extensions, including `hash_map` and `hash_set`. Both of these were used in `GlassClipboard`'s Windows part. Because of this change, JavaFX does not build under Visual Studio 2026 18.6 and later.
This commit replaces deprecated `hash_map` and `hash_set` with STL-equvalent `unordered_map` and `unordered_set`. `GlassClipboard` also used (also deprecated) `hash_value` template function to calculate hashes for non-standard WinAPI object `_bstr_t` and `FORMATETC` (the latter was implicitly generated by the extension). Those were also replaced with STL-endorsed `std::hash` specializations. No other changes were necessary. All tests on Windows 11 pass successfully after this change and manual testing showed no regressions. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - GlassClipboard: Replace hash_map and hash_set Changes: https://git.openjdk.org/jfx/pull/2198/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=2198&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8387337 Stats: 31 lines in 1 file changed: 19 ins; 0 del; 12 mod Patch: https://git.openjdk.org/jfx/pull/2198.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/2198/head:pull/2198 PR: https://git.openjdk.org/jfx/pull/2198
