   fyi, soft references are notorious for causing bad performance in heavily 
loaded systems. They increase the number of full GCs due to heap pollution and 
will be evicted when low on memory, which can cause thrashing. Not sure I 
understand well enough to advise except to always question whether a usage is 
justified.
