Back when the javax.lang.model API was being designed as part of JSR 269, while the API was primarily intended for use at compile-time with annotation processing, the expert group also wanted the API to be usable in other contexts as well, including at runtime.

Jonathan Gibbons: Shelling Tests

jjg — Fri, 17 May 2013 22:00:46 GMT

jtreg provides support for various different types of tests. API tests can use "@run main", simple compiler tests can use "@compile", and simple GUI or applet tests can use "@run applet". And then there's the ubiquitous "misc" or "other" category, for which "@run shell" is provided. However, there are a number of reasons why not to use "shell tests", and recently we made another ...

Gary Benson: VM networking tip

gbenson — Fri, 10 May 2013 09:37:06 GMT

If you are setting up VMs using libvirt then it’s a good idea to change the address of the virtual network to something other than the default. Why? Because if you don’t, and you create a guest which itself starts up libvirt and uses NetworkManager then at least some of the time your VM will [...]

The first was an OpenJDK TestFest, sponsored by the London Java Community, IBM, and Oracle. This wasn’t officially part of Devoxx. It was held at the […]

Gary Benson: Only dest dir longer than base dir not supported

gbenson — Wed, 08 May 2013 19:50:25 GMT

Hello, Have you experienced the mysterious error, “Only dest dir longer than base dir not supported”? I have. The Problem When you build an rpm, the code is built in %{_builddir}, which usually evaluates as %{_topdir}/BUILD, which in turn evaluates as something like /home/you/rpmbuild/BUILD. The built code (if built with GCC) ends up with loads [...]

Jim Laskey: jjs -fx

jlaskey — Tue, 07 May 2013 20:20:54 GMT

So after some playing around and working with the JavaFX folks, I think we have a proposal for jjs that works with JavaFX. The -fx flag on jjs will bootstrap scripts using a javafx.application.Application. Thus, writing JavaFX scripts in Nashorn is very easy.

Gary Benson: Saving money

gbenson — Wed, 01 May 2013 10:04:20 GMT

I have a pair of set-top box PCs I’ve been using as always-on servers. I used them because they’re silent, but lately I’ve been thinking about power consumption. They were pretty good when I bought them in 2006 and 2008, but there’s much better stuff available now. I spent £60 on a Raspberry Pi and some supporting [...]

It seems there are a lot of recipes for generating OpenJDK webrevs. Here's the one I use. I have been meaning to turn it into a proper script but have been too busy/lazy. I use the mercurial mq extension and am always generating webrevs for mq patches. ...
