Description

From Christof Lorenz on the users mailing list

I saw that the inflater's end() method is being called in FlateFilter.decompress.
But our tests are showing inflaters not being closed, that were opened by FlateFilter.decompress.
I think the inflater.end() should be called in a finally block to really close them all.
