Update of /cvsroot/exist/eXist-1.0/src/org/exist/util
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv18976/src/org/exist/util

Modified Files:
	XMLString.java FixedByteArray.java 
Log Message:
Fixed class LRUCache. LRUCache is now used for the data pages in DOMFile + BFile. LRU seems to be a better strategy for the data pages than
LRD. It produces less page failures.
