Matt Kusnierz commented on IO-480:
----------------------------------
I have tried to raise this with Oracle through my support companies support
contract; and they appear to be reluctant to fix this in the FilterInputStream.
The closeQuietly method says that it should silently swallow ANY / all
exceptions; so I still think that it makes sense to fix this within IOUtils.
> IOUtils.closeQuietly can throw NullPointerException

> Key: IO-480
> URL: https://issues.apache.org/jira/browse/IO-480
> Project: Commons IO
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 2.4
> Reporter: Matt Kusnierz
> Original Estimate: 10m
> Remaining Estimate: 10m
>
> The IOUtils#closeQuietly method in its javadoc suggests that ANY exceptions
> will be ignored. This is not the case, as the code only catches IOExceptions.
> As this example stack trace shows, it is possible for some InputStreams to
> throw NullPointerExceptions during close:
> java.lang.NullPointerException: null
> at java.io.FilterInputStream.close(FilterInputStream.java:155)
> ~[na:1.6.0_35]
> at
> sun.net.www.protocol.jar.JarURLConnection$JarURLInputStream.close(JarURLConnection.java:90)
> ~[na:1.6.0_35]
> at org.apache.commons.io.IOUtils.closeQuietly(IOUtils.java:281)
> ~[commons-io-2.1.jar:2.1]
> at org.apache.commons.io.IOUtils.closeQuietly(IOUtils.java:224)
> ~[commons-io-2.1.jar:2.1]
> Close quietly should do as advertised/suggested and catch all Exceptions.
