If the routines are not properly translating characters to uppercase,
that could very well be a bug in the JVM. I would follow up with Sun.

Also, I would also check out some things concerning the Locale. For
example, did you try the other constructors as well? Did you try the
Locale.getAvailableLocales() method to see if the one you want is
actually installed and supported?

Another thought, a possible workaround might be to use toLowerCase() if
that is more well behaved.
