Error under Ubuntu with the method String.join

Question

I use the lib commons-lang-2.4.jar for my project. I develop under Windows, then send everything (including those libs) to Ubuntu server 4.6.3 Under windows, everything works fine. But when I launch my program under Ubuntu, I get this error:

java.lang.NoSuchMethodError: java.lang.String.join(Ljava/lang/CharSequence;[Ljava/lang/CharSequence;)Ljava/lang/String;

How can I fix it?

Your exception shows that you are calling join on a string(java.lang.String) object. I don't think String has a join method. But this should be shown as compile error in eclipse. How are you coding your project? — Nazgul, May 01 '14 at 17:38
@Nazgul - `String` has a `join` method, but it was only introduced in JDK 1.8. — Mureinik, May 01 '14 at 17:42

String.join was only introduced in Java 8 (JDK 1.8). Your windows machine apparently has it, while your ubuntu machine has an older version of the JDK installed. This has nothing to do with their respective operating systems or commons-lang-2.4.jar.

TL;DR - upgrade to JDK 1.8 on your ubuntu machine.
