weird warning about invalid UTF-8 characters in java comments ...

Hi, i found following 2 files creating compilation warnings on java 1.5 if
the shell variable LANG=de_DE.UTF-8 :

compile:
    [javac] Compiling 581 source files to target/scarab/WEB-INF/classes
    [javac] 
src/java/org/tigris/scarab/om/GlobalParameterManager.java:66: warning: 
unmappable character for encoding UTF8
    [javac]  * @author <a href="mailto:[email protected]">Ronny 
V�lker</a>
    [javac]                                                           ^
    [javac] 
src/java/org/tigris/scarab/services/cache/JCSScarabCacheService.java:24: 
warning: unmappable character for encoding UTF8
    [javac]  * @author <a href="mailto:[email protected]">Ronny 
V�lker</a>
    [javac]                                                            ^

The effect disappears, when i change the shell variable LANG=de_DE

I am not sure, why java complains about characterset-problems within 
comments. I have never seen this.
But ok, maybe Ronny agrees in replacing his name by "Ronny Voelker" so 
the warnings don't appear ?
And we agree on using utf-8 character set only in the java sources ?

hmm... as i said, this is weird and i would say, that' can't be, if i 
wouldn't have seen the effect with my
own eyes. Am i too picky ? But i am fan of the principle "No message is 
good message" at least during
compilation ;-) ...

regards,
hussayn
