Interesting coincidence:
That's exactly what Andreas already wrote about in the other thread
about the property cache: The values of the WeakHashMap must not
reference objects (or be the same objects) as used in the keys. See
javadoc:
http://java.sun.com/j2se/1.3/docs/api/java/util/WeakHashMap.html
But that's exactly how PropertyCache is implemented right now.
In addition to that there was a bug in FixedLength.equals() that made
the caching effect-less:
