If it remains in scope it won't be GC'ed, so something unexpected is probably happening that makes you think it's in scope. The 100% certain way of making sure an object is not collected by the GC, is to store it in a static variable (but ensure you clear out the variable once you're done with it, since otherwise the GC will never free the object).
