Upgrading existing Java Project from Java 1.6 to 1.8
<p>Recently I was assigned to a task wherein I have to upgrade the existing standalone java application from <strong>Java 1.6</strong> to <strong>Java 1.8</strong>. <br>
I'm yet to go through the code and I have no idea about this project. </p>

<p>They were using 
ANT 1.6.1, <br>
AXIS 1.5.1, <br>
ABINITIO 2.15, <br>
ORACLE 11.1.0.7, <br>
AUTOSYS R11, <br>
Java 1.6.<br></p>

<p>I got to know that first I need to identify whether the above mentioned Tools/Frameworks are compatible with Java 1.8. <br></p>

<p>Please suggest what are the other challenges I might encounter while compiling and building the application?</p>
