I really got no OOM.
So, the impression I have is that there is some kind of cache static who
uses the free memory for the IndexSearcher, if I set -Xmx16m the application
uses the entire 16m, if a set -Xmx512m after some time the application uses
the entire 512m, the way that even if a instanciate a new IndexSearcher this
cache is not cleaned.
Am i right ? If yes, is there some parameter or method where i can free or
control that ?
Thanks

Did you try what was suggested? (-Xmx16m) and did you get an OOM? If
not, there is no memory leak.
