Description Quy Nguyen 2007-12-06 19:45:19 UTC 
From the HeapWalker analysis of a heap dump, FacesDesignProperty objects seem to hold onto redundant objects of type
Boolean in the 'initialValue' field.  There should only be two instances of Boolean (Boolean.TRUE and Boolean.FALSE). 
This is a minor waste of memory.
Comment 1 _ sandipchitale 2007-12-06 23:21:27 UTC 
I think this is because that value is used as a key in the hashtable...not sure though.
Comment 2 Quy Nguyen 2007-12-06 23:48:31 UTC 
That shouldn't make a difference, since Boolean.hashCode() only has two possible return values, based on whether the
object represents true or false (see hashCode() javadoc for the Boolean class).
Comment 3 _ sandipchitale 2007-12-07 18:32:42 UTC 
You are right. I meant to say that the == is used somewhere to detect distinct values. I need to check on it.
