FileFilterUtils can create cvsFilter and svnFilter more than once
-----------------------------------------------------------------
Key: IO-240
URL: https://issues.apache.org/jira/browse/IO-240
Project: Commons IO
Issue Type: Bug
Reporter: Sebb
Priority: Minor
FileFilterUtils lazily creates the static fields cvsFilter and svnFilter;
however access to the fields is not synchronized and the fields are not
volatile.
One thread can create the filter, but the updated value won't necessarily be
seen by any/all other threads.
This means that the fields can be created multiple times.
Possible solutions: make the fields volatile, or use the singleton IODH idiom.
The latter uses a bit more code, but is probably marginally cheaper if the
field is used a lot.
