> The FileUtils.writeByteArrayToFile method does not allow a subset of an array to be written
to a file.  Instead, the subset must be copied to a separate array, increasing the lines of
code and (for all JVMs I know about) runtime.
> Sister methods that take an offset and length should be added, inline with the byte array-oriented
methods in the Java standard library. 
> Attached is a patch that implements FileUtils.writeByteArrayToFile(File file, byte[]
data, int offset, int length) and FileUtils.writeByteArrayToFile(File file, byte[] data, int
offset, int length, boolean append) and associated testcases in FileUtilsTestCase.java.
