    Why are you using wait() here? A sleep should be enough. I don't think this needs to be in a synchronized block either - would more than 1 thread try to close the same file?

    The loop already checks that you try invoking close only a fixed number of times.  Also, currently we don't throw an exception if we could not close the file - I guess we should just keep the same semantics - catch it and log.

    Is this new method really required? Does not look like it is.

    I don't see this class anywhere in the patch, maybe missed a git add?
