Application: telephone directory inquery services for 1/3rd of Hungary,
software is written in Java 1.2 with Swing classes, running on SunRays.

Problems description:

Java 1.2.2_06 JDK with Swing and only with Swing produces the following
input method problems under the hu_HU.ISO8859-2 locale:

Keys a,e,i,o,u,÷,M-^R pressed with Shift does not produce any capital
Â,Ð,Í,Ô,õ,Ù,M-^[ letters in input fields at all. The special letters of long ÷ and
M-^R (long umlaut o and u) pressed together with Shift - capital letters - appear
just fine. If CapsLock is toggled, all the capital letters of Â,Ð,Í,Ô,õ,Ù,M-^[
are shown in the input field when the corresponding keys have pressed.

The problem was reproduced on standalone Sun workstations and on SunRays
as well.

Conclusion, this is not a SunRay server related bug.

Any standard application not using Java and Swing does not produced
the problem.

Conclusion, this is a Java related bug.

The same Sun JDK on Windows does not produces the problem described
above.

Conclusion, this is a Solaris JDK bug.

The same application with AWT GUI elements does not produced the problem.

Conclusion, this is a Swing bug.

The problem does not appeared, if the capital characters have been typed into
any non-Java text field (eg. into a text editor) than copy-pasted into the
Java Swing text input field.

Minimal demo application was written to test the bug, the content of the Swing
input field was saved into a text file. This text file has not contained any
of the typed, but not displayed capital special Hungarian characters, so it is
not a rendering problem in the input field widget.

The above described test shows that the problem is probably in the Solaris
JDK Swing implementation. Since the letters appeared with CapsLock, this is
probably a keystroke event handler bug in the Swing input method classes.

Reproduction: you can easily reproduce the bug. You can write an approx. 10
lines long code in Swing and in AWT with an input field and try to type there hungarian characters under hu_HU.ISO8859-2 locale and (hopefully) the problem
will occur.
