XSetICValues() fails with XNPreeditState in Java_sun_awt_X11InputMethod_setCompositionEnabledNative in awt_InputMethod.c on Linux (Solaris on both sparc & x86 return successfully)
Tried on RHEL 4 u1.

However, no malfunctioning is seen with the applicaiton that uses input method.
It needs to be investigated further.
