---------------------------------
Summary: The use of file.exists() is failure prone. Where
file.exists() is checked, it should be replaced with the following dual check:
exists = ( file.exists() || file.length()>0 )
Key: IO-340
URL: https://issues.apache.org/jira/browse/IO-340
Project: Commons IO
Issue Type: Bug
Components: Utilities
Affects Versions: 2.5, 3.x
Environment: All
Reporter: Wilf Middleton
Fix For: 2.5, 3.x
The use of file.exists() is failure prone. In many cases the jvm can report
that a file does not exist even when it does. This is due to the caching in the
operating system.
Since file.exists() is prone to report false values, a second check can and
should be made to file.length()>0.
Where file.exists() is checked, it should be replaced with the following dual
check:
A file more reliably exists if: file.exists() || file.length()>0
Then if the file does not exist, file.length will be 0.
