Hi Mikhail,
I have seen the J2SDK code, and now I believe your problem isn't
really a problem of J2SDK but of X11's ru_RU.KOI8-R supports.

If you are interested in the fact, please see the source code.
at j2sdk1.3.1/src/solaris/native/sun/awt/awt_MToolkit.c:1515
if (!XSupportsLocale()) {
jio_fprintf(stderr,
"current locale is not supported in X11, locale is set to C"
);
setlocale(LC_ALL, "C");
}
The XSupportsLocale() call must return False if Xlib locale-dependent
functions are not capable for current locale. Your case,
ru_RU.KOI8-R, may be the case False to be returned, but it doesn't
return False. Therefore, awt skips to setlocale(LC_ALL, "C") and as
the result, XOpenIM(...) -- a Xlib locale-dependent function returns
NULL at j2sdk1.3.1/src/solaris/native/sun/awt/awt_InputMethod.c:1071.
It means that XOpenIM failed. For locales that Xlib locale-dependent
functions are capable, XOpenIM fails only when current locale needs
XIM server to input text in the language specified by current locale
*AND* the XIM server isn't available. This is the case can be happen
in Chinese/Japanese/Korean environment. For English or some other
language using latin characters environment that are well supported in
X11 may never fail.
I'm not sure about Russian environment. Does setting LANG=C for java
cause any problems for you?
