    Are you sure the memory is occupied by Jxls or POI related objects?

    Can you do a heap dump or memory profiling to prove that?

    Can you create a simple app or web-app where I can reproduce the issue?

    Just from the issue description and without any working sample it will be really difficult to do anything about it.
