<div dir="ltr">The language improvements in Java 7 are quite minor
(syntactic sugar). None of them are worth preventing new features from being included in the applets. The RCSB applets are very widely used and can't (well, shouldn't) just dictate that users upgrade java to use the website features. Even without the RCSB, I think as a library it is not our place to "encourage" users to upgrade their code. Breaking backwards compatibility should be seen as a negative thing that is only done when clearly outweighed by substantial benefits.<br><br>The 1.8 language additions might be significant enough that we'll one day want to break backwards compatibility in order to use lambdas in our API, but it will take years for 1.8+ to saturate the market.<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Oct 8, 2014 at 12:35 PM, LAW Andy <span dir="ltr"><<a href="mailto:andy.law@roslin.ed.ac.uk" target="_blank">andy.law@roslin.ed.ac.uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">You are talking about what version of Java to work against for the forthcoming 4.x releases.

You will not be cutting away existing functionality from current software.<br>
<br>
Go 1.7 and encourage those who want to use biojava jars but haven’t already upgraded their code to fit 1.7 to do so if they want the benefits of the new code.<br>

IMHO, of course.<br>

I'm not very sure, this could be not an issue if they refer to the vm itself programs (since old compiled code can be executed by newer releases), but it could be if they refer to fixes to the system library. Anyone has an opinion about that?<br>

If we would upgrade to 1.7 we would break biojava derived applets and Java web start for these. As such I'd vote for staying conservative and to NOT upgrade to 1.7 at this time, in particular since there is no strong reason for the move. Less than 2% of users seem to be using 1.8 currently.<br>
