Hello Vladimir.

I really appreciate your help.

"XMODIFIERS=@im=local" is related Multi key Compose feature [1]
One of document said "XMODIFIERS=@im=none" [2]

Could you try "XMODIFIERS=@im=none" ?

Hello
I’m getting Bus Error on startup with
XMODIFIERS=@im=local ./xim_root
nothing yet in log at that moment.

Thanks, Vladimir

Hello Vladimir.

I appreciate your reply.
I did not expect "[1]w=0x0", it means xim_root could not receive focus window via XIC. I checked ibus XIM server on Linux s390x platform again, it also returned "[1]w=0" ... 
I was confused.

I'd like to add new instruction
5. Run xim_root with XMODIFIERS=@im=local environment variable on desktop, like 
  $ XMODIFIERS=@im=local ./xim_root
6. Move input focus to XIM demo window
7. Press Ctrl key and Press Right mouse button

I tested xim_root on Linux s390x platform.

$ XMODIFIERS=@im=ibus ./xim_root
fevent = 0x3
topwindow = 0x1e00001, window = 0x1e00002

I was expected this result.

I'm sorry, it seemed current code did not work on even if Linux s390x platform.

Hello
I’m probably missing something about XIM on X side here, using ssh
-X from ubuntu(with Xserver) to solaris11 sparc64 machine
the output is

I also had to press left button, not right one.
I think when you initialy created 8213232 you were targeting linux
ppc64 BE system in your patch and simply forgot about another 64-bit
BE system - solaris sparc64
I would propose this fix for 8227919
--- a/src/java.desktop/unix/native/libawt_xawt/awt/awt_InputMethod.c
+++ b/src/java.desktop/unix/native/libawt_xawt/awt/awt_InputMethod.c
@@ -1671,7 +1671,7 @@
{
    X11InputMethodData *pX11IMData = NULL;
    char * ret = NULL;
-#if defined(_LP64) && !defined(_LITTLE_ENDIAN)
+#if defined(__linux__) && defined(_LP64) && !defined(_LITTLE_ENDIAN)
    // XIMPreeditState value which is used for XGetICValues must be
32bit on BigEndian XOrg's xlib
    unsigned int state = XIMPreeditUnKnown;
#else
Such change already allowed to pass our internal tests on solaris sparc64 
if you think it’s ok then let me take over and finish with 8227919
Thanks, Vladimir
