DictionaryCompoundWordTokenFilter Flag onlyLongestMatch has no affect [LUCENE-3022]

When using the DictionaryCompoundWordTokenFilter with a german dictionary, I got a strange behaviour:
The german word "streifenbluse" (blouse with stripes) was decompounded to "streifen" (stripe),"reifen"(tire) which makes no sense at all.
I thought the flag onlyLongestMatch would fix this, because "streifen" is longer than "reifen", but it had no effect.
So I reviewed the sourcecode and found the problem:
[code]
protected void decomposeInternal(final Token token) {
// Only words longer than minWordSize get processed
if (token.length() <this.minWordSize) {
return;
}

char[] lowerCaseTermBuffer=makeLowerCaseCopy(token.buffer());

for (int i=0;i
