Sanjiva,

Just to explain a bit :)

A leak is when the method is finished the memory cannot be GC'ed.
"consuming the memory unnecessarily" means that during a method's
execution, it's taking more than appropriate what is needed :) Example
http://issues.apache.org/jira/browse/AXIS2-264 is not a leak.

thanks,
dims
