------------------------------

             Summary: ThresholdingOutputStream.thresholdReached() results in FileNotFoundException
                 Key: IO-512
                 URL: https://issues.apache.org/jira/browse/IO-512
             Project: Commons IO
          Issue Type: Bug
          Components: Streams/Writers
    Affects Versions: 2.5
         Environment: java8  debian
            Reporter: Ralf Hauser


I upgraded from commons-io-2.0.1.jar to v2.5 (and fileupload to v1.32)

and now I get

java.io.FileNotFoundException: /usr/share/tomcat/temp/dfifp/upload_4d9f8898_1a83_4092_9070_ddf9c15de6d1_00000027.tmp (No such file or directory)
	at java.io.FileOutputStream.open(Native Method)
	at java.io.FileOutputStream.<init>(FileOutputStream.java:213)
	at java.io.FileOutputStream.<init>(FileOutputStream.java:162)
	at org.apache.commons.io.output.DeferredFileOutputStream.thresholdReached(DeferredFileOutputStream.java:179)

In thresholdReached(), the prefix is null, so no temp file is created.
In the subsequent new FileOutputStream(outputFile), the exception is thrown.

Suggested fix:
before new FileOutputStream(outputFile) , add

FileUtils.forceMkdirParent(outputFile);
