Subject: [bug]commons-io 1.3 FileUtils.openOutputStream(File file) NullPointException

FileUtils.openOutputStream(File file)
When the file = new File( "abc.txt" );
There will be a NullPointerException throw.
Cause
file = new File("abc.txt")
file.getParentFile() returns null.

So I suggest adding the null check code like this.

File parent = file.getParentFile();
if( parent Unable to render embedded object: File (= null ) { // ADD THIS) not found.!!
if (parent.exists() == false) {
if (parent.mkdirs() == false)

{ throw new IOException("File '" + file + "' could not be created"); }

}
}

Xinzi ...
