Hello, looks like libwindowsaccessbridge has some issues in native coding on 64bit Windows , probably it was developed with 32bit in mind And still misses a few adjustments.
WinAccessBridge .h/cpp contains BOOL CALLBACK AccessBridgeDialogProc(HWND hDlg, UINT message, UINT wParam, LONG lParam); and theDialogWindow = CreateDialog(windowsInstance, "ACCESSBRIDGESTATUSWINDOW", NULL, (DLGPROC) AccessBridgeDialogProc); But DLGPROC has parameters ( https://docs.microsoft.com/en-us/windows/win32/api/winuser/nc-winuser-dlgproc ) HWND Arg1, UINT Arg2, WPARAM Arg3, LPARAM Arg4 So probably the 3rd and 4th params should be ... WPARAM wParam, LPARAM lParam . One internal user claimed to have crashes because of this type mismatch . Additionally I found some unused declarations in WinAccessBridge.h probably we could delete them . Bug/webrev : https://bugs.openjdk.java.net/browse/JDK-8249588 http://cr.openjdk.java.net/~mbaesken/webrevs/8249588.0/ Thanks, Matthias
