Xtend 2.5.1

[Sven Efftinge]

Hi all,

Xtend 2.5.1 is now available. It’s bugfix and performance release.
Here’s the list of issues addresses in this release.

https://bugs.eclipse.org/bugs/buglist.cgi?status_whiteboard=v2.5.1

The next release 2.6 is planned for end of May.
This is what’s on the plan (we won’t be able to do all of that):

https://bugs.eclipse.org/bugs/buglist.cgi?status_whiteboard=v2.6

Cheers,
Sven

Good work! Installing now, thanks.

[Vlad Dumitrescu]

Hi Sven,

Great work!

There is one thing that is probably not a bug as such, but might be something to look at: I updated the xtend.lib and xbase.lib in my project to 2.5.1 before updating the installed Xtend version. There were plenty of errors, but that was expected. What was unexpected was that there were exceptions in the JDT compiler (presumably because of that mismatch, they went away after upgrading). Some NPEs didn't have any xtext/xtend stuff on the stacktrace, but one did, see below.

best regards,

Vlad

[Sebastian Zarnekow]

Hi Vlad,

thanks for the feedback. It's unfortunate but JDT dumps these *expected* problems to the console internally and there's no way to avoid that on our side. It doesn't manifest in any misbehavior that we are aware of.

Best regards,

Sebastian

Ok, I understand. The problem for me was that the compiler also opened a popup dialog about the exception and I got confused for a while. If it's not a sign of a possible internal problem, then it's ok for me. 

regards,

Vlad

[Sebastian Zarnekow]

Oh, you shouldn't see such a dialog at any time. I understood that you used 2.4.3 or 2.5.0 with 2.5.1 on the class path? There were a couple of issues that could present that dialog to the user with 2.5.0. I don't think that one is reproducable for you with 2.5.1?

Regards,

Sebastian

[Vlad Dumitrescu]

Yes, I had 2.5.0 installed in Eclipse and the project libraries had been updated to 2.5.1. With 2.5.1 installed there are no errors at all, the classes are found. If I try with 2.5.1 and the 2.5.0 libs, there are some validations errors in the logs, but no JDT exceptions.

regards,

Vlad

Thanks, great work guys! And very helpful to see what has changed and what's in the pipeline :-)
