Holger Hoffstätte commented on LANG-324:
----------------------------------------
In light of the many problems with FileCleaner (in IO and FileUpload) I would
like to suggest that libraries like commons-lang and commons-io *never* create
Threads, or - as is the case here - a Timer. It would be much better to let the
user inject the Thread/Timer/ScheduledExecutor(!) in the constructor, otherwise
the class has to manage a stateful objects' slifetime without any good means to
do so. Also, Timer itself is not such a great idea to begin with;
ScheduledExecutorService in JDK5+ and the backport lib is much more predictable
and well-behaved, so making the actual timing mechanism pluggable/replaceable
has high value.
