      Description

        According to the Windows API reference[1], dwStyle of CANDIDATEFORM structure should be set to CFS_CANDIDATEPOS or CFS_EXCLUDE. So, CFS_POINT is wrong here.
          
        See line 3914 in src\java.desktop\windows\native\libawt\windows\awt_Component.cpp [2], AwtComponent::SetCandidateWindow function:
                CANDIDATEFORM cf;
                cf.dwStyle = CFS_POINT;
                ImmGetCandidateWindow(hIMC, 0, &cf);
