New Revision: 1634708
URL: http://svn.apache.org/r1634708
Log:
If the exception is thrown then current will be null.
If current is null then popFile() is a NO-OP.
Since popFile() is only called in the exception handler it can be
removed. Also remove the other code the IDE marks as unused once
popFile() is removed.
