ResourceBundle.getString() throws ArrayIndexOutOfBoundsException

Question

Hi Everyone.
I am getting "java.lang.ArrayIndexOutOfBoundsException: 1" when I try to call ResourceBundle.getString():
ResourceBundle rb = ResourceBundle.getBundle("full.package.name.StringsBundle");
String s;
try {
    s = rb.getString( key_that_i_am_pretty_sure_really_exists_in_StringsBundle_and_is_really_a_string );
} catch ( Exception e ) {
    s = "Exception：" + e.toString();
}s always ends up as "Exception： java.lang.ArrayIndexOutOfBoundsException: 1"
According to the javadoc, getString() can throw NullPointerExceptions or MissingResourceExceptions or ClassCastException, but not ArrayIndexOutOfBoundsExceptions... and the Exception doesn't make any sense to me in this context...
Could this be a bug in the ResourceBundle implementation? Or is there something really stupid I am missing or what do you think?
Thanks,
Bishop

Thanks for the lead about the character compatibility. I will look into that more. It sounds likely since the strings I am trying to look up in the bundle have kanji in them.
Here's the stack trace (some package/class/variable names slightly obfuscated). The rogue exception is indeed being thrown by the ListResourceBundle implementation code.
