> A race condition can occur in SessionPathResolverCache since the internal cache is initialized with a non-threadsave HashMap.
> Under websphere we can observe blocking threads while accessing the map at:
> ...
> at java/util/HashMap.findNonNullKeyEntry(HashMap.java:601(Compiled Code)) 
> at java/util/HashMap.getEntry(HashMap.java:585(Compiled Code)) 
> at java/util/HashMap.get(HashMap.java:571(Compiled Code)) 
> at org/apache/jetspeed/decoration/caches/HashMapPathResolverCache.getPath(HashMapPathResolverCache.java:49(Compiled Code)) 
> ...
> The base class HashMapPathResolverCache is not used and can be removed completely, all methods can be migrated to SessionPathResolverCache.
> Additional a spelling typo has been fixed.
> patch follows...
