Sebb resolved IO-622.
---------------------
Resolution: Information Provided
There used to be just one readLines method with two parameters:
FileUtils.readLines(File, String encoding)
There are now two such methods:
FileUtils.readLines(File, String)
FileUtils.readLines(File, Charset)
The compiler can no longer determine whether the null parameter is a String, or
a Charset.
You will have to change the source and recompile.
e.g.
FileUtils.readLines(TestFile, (String) null);
Note that the additional method does not affect binary compatibility.
[The compiled code includes the method signature, so the JVM can find the
correct method to call.]

> Hi,
> The following code snippets throw an incompatible issue when I try to rolling
> update Commons IO to 2.6. It works well before 2.3.
> {code:java}
> @Test
> public void DemoTest(){
> List<String> l = new ArrayList();
> File TestFile = new File("TestFile");
> try {
> l.addAll(org.apache.commons.io.FileUtils.readLines(TestFile, null));
> } catch (IOException e) {
> e.printStackTrace();
> }
> }
> {code}
> Thanks a lot.
