Under this model, you can't actually store a ref to the thing to be GCed in the <tt>Runnable</tt> that you register (in this case the builder proxy), b/c any ref stronger than a <tt>PhantomReference</tt> will preclude GC in the first place. So you would have to pass something that allows you to effectively return/reclaim the builder... without actually having a reference to the builder.</p> <p style="margin: 10px 0 0 0">Only thing I can see that would suffice is an index/id value to the wrapped builder. However, in the pool we don't currently maintain any state about builders that have been created and which are currently "checked out". So in order to support this case, we'd have to start doing all that - maintaining a map of ID -> builder, or similar. There's a certain amount of complexity to that, and dealing with the edge cases of multiple checkins, the "normal" case of the caller returned + later it's also GCed, etc.</p> <p style="margin: 10px 0 0 0">It doesn't seem worth all that just to avoid "losing" a builder. Better to just do some logging as Scott says, and perhaps some auditing that we aren't omitting the return.</p> <p style="margin: 10px 0 0 0">And on the latter point... A quick search confirms my suspicion that none of the code in my workspace even uses the <tt>getBuilder()/returnBuilder()</tt> interface pattern. We always use the other convenience methods on the interface - <tt>newDocument(), parse(...)</tt>, which internally do the right thing always.</p> <p style="margin: 10px 0 0 0">So I'm 99.9% that we just remove the finalize, check and maybe add some logging, and move on.</p> </td>
