FWIW, this is what dumpbin displays for these entries:
1 2 0000351C addAccessibilityEventNotification =
?addAccessibilityEventNotification@WinAccessBridge@@QEAAX_J@Z (public: void
__cdecl WinAccessBridge::addAccessibilityEventNotification(__int64))
2 4 00003628 addJavaEventNotification =
?addJavaEventNotification@WinAccessBridge@@QEAAX_J@Z (public: void __cdecl
WinAccessBridge::addJavaEventNotification(__int64))
3 42 00006D94 removeAccessibilityEventNotification =
?removeAccessibilityEventNotification@WinAccessBridge@@QEAAX_J@Z (public: void
__cdecl WinAccessBridge::removeAccessibilityEventNotification(__int64))
4 44 00006EA0 removeJavaEventNotification =
?removeJavaEventNotification@WinAccessBridge@@QEAAX_J@Z (public: void __cdecl
WinAccessBridge::removeJavaEventNotification(__int64))
There's no way to get a pointer to an instance of `WinAccessBridge` using the
supported interface, and calling these methods with garbage value for `this`
would likely crash.
